#342982 Mondeo Brakes

Posted by BOF on 15 March 2014 - 12:37 AM

Hi there, I have a bit of a problem with the brakes on my 2.5T titanium X.

 

I did a fast run on the way home the other night, 6 miles, 10 corners. By the time I was home, the brake pedal was hard and they had virtually stopped working. When I got out of the car they were stinking.

 

 

 

When you say that the 'brake pedal was hard', you do mean that you felt resistance in the normal position in the brake pedal travel, but the feeling was 'wooden' and it didn't cause much braking? If the pedal had sunk down, it would be a totally different diagnosis.

 

Firstly, you can fade the brakes on any production car if you try hard enough...However, if you can't do at least one stop from Vmax safely without the brakes going away, the car isn't safe to drive to that speed.

 

Given that there are two broad categories of fade (fluid 'boiling' and the various brake pad problems - here, probably overheating), if we can eliminate 'fluid', then we've got pads and temperature.

 

(You'll probably still have to change the fluid, for one of two reasons

  • this process has abused the fluid enough so that you can't trust it
  • you can't trust that the fluid was in decent condition, after its previous life, possibly at the hands of someone who thought saving money on brakes was smart and who possibly either fitted sub-standard fluid or left it too long between changes

It doesn't sound as if fluid was your immediate problem though, depending on the interpretation of the pedal symptom.)

 

Brake pads and materials are a compromise - there is not a magic 'just fit this, and all problems go away' solution. That said, it does sound as if you can find something more suited to your requirements.

 

It was both front wheels that were hot.

 

Sticking brakes are more common at the back than the front, so assuming that we can eliminate that (...ideally, you do some more testing...) then the temperature isn't being raised by sticking, then it should be possible to get an improvement by changing pads. Enough? Get the improvement without introducing other problems? These are good questions, and, ultimately, you won't know until you've tried. Bigger brake disks would also help get rid of the heat, but it is unclear whether you need to go that far.

 

(BTW, you say that it was the front wheels that were hot. Does that mean that the rears weren't hot at all, or were they just substantially less hot than the fronts? If the rears are doing no work in stopping the car, that will put all of the effort on the fronts and will make the problem worse.)

 

(Also, I need to make a comparison with tyres here - there is no point in saying buy this brand of pads; most pad manufacturers make several ranges, and buying the 'bog standard' pads from someone who also makes performance pads probably won't help, just as buying tyres by brand doesn't help.)

 

So, for example, EBC, who you mention, make a 'comparable with OEM quality' pad - I'm pretty sure this is a negligible improvement over the atandard OEM pad. You would need, for example, to be in with the yellowstuff and redstuff 'performance' pads before you get a worthwhile improvement over OEM. Redstuff may even need a little warming before it really bites, so this is where the compromise comes in - are you prepared to suffer that in order to get a pad that keeps working to higher temperatures?

 

Note also that the bigger wheels on a TitX should allow a slightly bigger disk...but be careful, if you would ever intend ton go down in wheel size, eg, to fit winter tyres.

 

One thing that is worth looking out for is whether you can see any manufacturers ident on the back of the pad (Ford, Ate, etc). If you can see that, and it is one of the respectable makes, it probably isn't 'cheapskate fitted inadequate pads'. If you can't see any ident, then it might just be inadequate pads, and, in that case, going to OEM quality might be a step forward (although, you might still want a bigger step than that).

 

My feeling (ie, guess) is that you will end up with a slightly bigger wheel size and slightly better pads, but i don't know how to be sure whether, eg, just slightly improved pads will do the job.

 

Edit:

I should have commented on the possibility that you have glazed your pads - however, as the cure for this is often suggested as giving the pads a serious work-out, I originally felt that this removes the glazed pad possibility. This is wrong; you could have glazed the pads so badly that even a work out such as above has not been able to get the pads back to normal operation. 




#316858 What Tyres For My Focus?

Posted by BOF on 01 January 2014 - 09:18 PM

I have uniroyal rainsport 2 225/40 /zr18s @£79 each plus £2.99 per tyre delivery next day

 

RS2s aren't as good as RS3s, but that's a very good price. A really good price.

 

 

I recommend to try thi site, as I believe they're cheaper than blackcircles,
www.camskill.com tyres

 

There is no one tyre site that is always the cheapest; you need to look at several, because one might be cheapest for, say, Hankooks and another for Michelins. That said, on average, Camskills is often one of the cheaper ones.

 

 

 

I ended up going through Tyreshopper for the best price.

 

 

I've also used Tyreshopper, and found them good. Price included fitting at National Tyres (and way cheaper than buying the exact same tyres bought through National Tyres).

 

As predicted, National tyres, who can't have been getting much dosh out of the deal, attempted to sell me something else, rear brake pads. As unexpected, it turns out that I actually needed rear brake pads.

#304686 Winter Tyres

Posted by BOF on 12 November 2013 - 11:57 AM

I just wanted to add a few little things to the sensible points above:

  • Not all summer tyres are the same and not all winter tyres are the same. Some Summer tyres are really bad on snow (I think, maybe, primarily the ones that come from the countries, such as Germany, where Winter tyres are 'de rigeur' and Summer tyres aren't expected to ever see snow) and some Summer tyres are merely 'not so good'. Equally, the cheap Winter tyres  tend to be less good than the expensive ones, and while even cheap Winter tyres can be ok on snow, that's not all that you are expecting them to do - you will likely leave them on for the coldest three or four months of the year, and they will be expected to cope with all the conditions that occur in that time, and those conditions will include more 'cold and dry' and 'cold and wet' days than actual snow. This is where the cheap Winter tyres often fall down - performance on the more normal conditions. (Of course, ignore that if you only fit them for a couple of days when someone has actually Tippexed out the landscape - changing tyres just for snowy days is a pain, though.)
  • In 'Auto Express' (warning: a video) they also had success, surprisingly, with a 'spray'. Now, tyre compound softener sprays have been existing for quite some time, but I was as surprised as they were that the spray they tested gave a big improvement. Softening the rubber must have an impact on wear, but I'd hate to guess how much. Like the 'sock' could be a worthwhile last ditch (sorry!) measure, if you don't find the ditch before you apply the spray.



#303404 Ford Mondeo 2.0 Tddi Starter Mortor And Engine Problems

Posted by BOF on 08 November 2013 - 11:50 AM

Well, it looks like the problem. I can only guess that the old DMF was disintegrating and shed that bit of metal before it finally died, and it has been hanging around, waiting to get you, ever since. Really, though, that's just speculation.




#300799 Mk3 Mondeo 2.5 16V V6

Posted by BOF on 30 October 2013 - 09:52 AM

 

I think it was he meant well known problems.

 

That was my guess, too, but I still don't understand '2.5 16V V6'; that'll be the less popular 2.6666667 valves per cylinder engine, won't it :D

 

In any case, if you want a useful answer to the original question, you might want to tell what year and spec the car is, as that doesn't define it very clearly.




#297743 Battery Drain

Posted by BOF on 18 October 2013 - 01:40 PM

You seen to know more about these things then me. If my alternator is shot how come i can use the car for 2-3 days without the battery dying? If it wasn't getting a charge surely it would die alot sooner??

 

You are probably getting some charge. In daytime driving (no lights, no a/c, no heated windows, no heated seats) the car current consumption isn't that high, although it does climb markedly if you switch those big electrical loads on. Given the capacity of a battery, you take some time to 'wear it down', and if you are even putting a small average current into it, that will take longer.

 

The exact current:voltage profile of the alternator can only be guessed at, but the battery isn't getting enough charge overall. You have to look at your other thread for the critical information:

 

@rusty123, here

I had to go worcester in it today. It started ok round go there,when i started it to come home,you could hear the battery was struggling a bit and then on way home the battery light came up on dash,about 5 mins later the abs light came on also then just before i got home those lights went off but the dials stopped working speedo,revs,petrol guage and temp.the when i parked up outside mine and turned the headlights off the dials started to work again .almost like it hadn't got enough power to power headlights and dash display at once. Oh and i tried to start it after i turned it off and battery is dead again

 

and

 

Managed to bump start it,drove it home about 25 miles away,tried it again outside my house as soon as id parked up and turned ignition off and nothing,completely dead. Didn't even attempt to start. 

 

but when the battery is flat, shortly after the vehicle has had an extended run, it isn't a low average current drain over an extended period (overnight or longer) that's doing it. If charging is working properly, 25 miles ought to be enough to get the battery substantially charged.

 

That said, you could probably also achieve this state by connecting up something that took 40+ amps all the time the car was running, and then even a good alternator wouldn't be able to keep up, but you might be able to find that on on dark nights by looking for the dull red glow-y thing under the bonnet. And it would need an almost heroic level of bad practice with the work on the starter to get there without having any idea that something was wrong. 

 

I put a multimeter on the battery just and it read 12.50 engine off and 12.30 engine on

 

With the engine running (that is what you mean, isn't it?) and no big loads running, the battery voltage should go up (slightly) and yours goes down. At that condition, the battery isn't getting as much charge as it should. Maybe it gets a more reasonable level of charge once the alternator is doing a few thousand rpm, maybe it doesn't. But then, who cares, provided that you fix the right fault?

 

If you don't feel happy with the advice that you've been given, just take it to a garage and pay them to fix it. That way, you'll have someone to complain at, if it goes wrong.




#296822 Spark Plug Choice

Posted by BOF on 14 October 2013 - 10:15 PM

I am goin to service my 1999 1.8 mondeo soon and was jus wondering if there would be any difference in putting better spark plugs in??

 

They'll probably last a little longer before they start going off. if you do a low annual mileage, this probably won't be an issue to you, as you'll probably change them anyway before things get too bad. Also, if you have, eg, cold starting problems, better spark plugs might make some difference...or they might not.

 

@L666JER

I use NGK or Bosch (preferably NGK). 

 

I've never had any problems with Bosch, but some people do complain about them, so, in general, I'd prefer NGK. Also used Denso, and have nothing bad to say about them, either (if that falls short of a rave review, that's deliberate; they are spark plugs, and you don't notice the things unless something is wrong).

 

@L666JER

 Castrol Magnatec or GTX

 

Castrol GTX Magnatec over plain GTX, imnvho. Or, anything that meets the -C spec over the -B (the last time I looked, anyway, the plain GTX only met -B)




#295633 Alloy Wheel Offset Question

Don't know anything about the wheels originally fitted, but does thiswebsite help you, at all?




#292250 Question For The Ice Guru's

Posted by BOF on 24 September 2013 - 07:07 PM

Are you saying that the Pioneer doesn't have any aerial power output?

 

In any case, you need the aerial powered any time you want to use the radio (which may be only when the car is running, or it may be at other times - one of the advantages of 'factory fit' is that the radio will just power on  for an hour without needing the ignition on - aftermarkets often don't do this).

 

You could power the antenna continuously - this would run the battery down a bit faster, but that may not be a big issue if you never leave the car for more than a couple of days without running it, but leave it at the airport for a couple of weeks, and that could be more tricky. Also check that the antenna is suitable for connection to the battery, which could have a wide range of voltages, and isn't only suitable for connection via some limited output from a radio.




#287584 Buying A Mk4 Mondeo...

Posted by BOF on 04 September 2013 - 10:08 AM

If you buy high mileage, then try to get the best service history that you can. Actually, have a look at the service record to see if anything nasty is lurking there (you know, repeats of any one fault, large numbers of 'random' faults, etc, etc).

 

Did the car get to the services on time, or was its arrival chez Ford a bit lackadaisical? As if someone didn't really care? 

 

Did it get there for all of its services (I saw one described as having a 'Full service history' that only made it for one out of every two of its scheduled services; Well, yes, I suppose it had a full history of the services which it had received, but that wasn't the issue...)

 

I find tyres are a good sign of how the car has been looked after; premium names are a good sign, as are the better mid-range options, but what you don't want to see are unknown Chinese tyres or weird wear patterns.
