Arkhangelsk1989 Posted January 11, 2021 Share Posted January 11, 2021 Hello I have a 2007 mk6 fiesta zetec s. I did a rear brake disc conversion on my car and accidently snapped a brake pipe while removing the union and this caused the reservoir to run empty. Ever since then the peddle has a slight soft spot before the brakes engage and it has been bled properly but can't seem to get this soft spot out of the peddle. Can you bleed Master cylinders seperately or does it bleed when you do the brakes using a pressure bleeder? Cheers for any help Quote Link to comment Share on other sites More sharing options...
stef123 Posted January 11, 2021 Share Posted January 11, 2021 Try pressure or vacuum bleeding. Next time, hold the brake pedal down with a piece of wood or something of that nature before you crack open anything. You’ll get a slight release of fluid and nothing more when you open a fitting. 2 Quote Link to comment Share on other sites More sharing options...

I had a garage do the bleed using one of them sealey hand pumps and they said all 4 calipers had no air or anything. Does a master cylinder need bleeding seperately or does a pressure bleeder clear all of the system? Cheers for the reply Quote Link to comment Share on other sites More sharing options...
Neb_engineer Posted January 11, 2021 Share Posted January 11, 2021 have you made sure that the ABS has been completley bled as air can get trapped in the ABS unit 1 Quote Link to comment Share on other sites More sharing options...

The brakes work well it's just there is a small amount of travel before the brakes begin too bite. Never had any trouble stopping, just wondering if this is normal or not.

Neb_engineer Posted January 11, 2021 Share Posted January 11, 2021 Just on the off chance that you have air trapped in the ABS (which can't be bled out with the ordinary style of bleeding) you should plug in a OBD interface and open all the abs valves through the software and then try bleed it 1 Quote Link to comment Share on other sites More sharing options...

Can you do that with any obd reader or is it a Ford garage only job? Quote Link to comment Share on other sites More sharing options...
Neb_engineer Posted January 11, 2021 Share Posted January 11, 2021 If you have an OBD to USB interface and forscan you should be able to do it yourself 1 Quote Link to comment Share on other sites More sharing options...

Can you bleed Master cylinders seperately or does it bleed when you do the brakes using a pressure bleeder? Cheers for any help There are two ways you can bleed brakes . One way where you can connect a pressure bleed to the master cylinder , it put pressure throughout the system and delivers fluid into the master cylinder as you realise each bleed nipple separately . you usually start the furthest away from the master cylinder and progressively closer to the master cylinder in turn. When the system has run dry it can take some time to get some of the air lock out . The second method is bleeding by pumping the brake pedal as each bleed nipple is released to bleed , the same as above only making sure you keep the master cylinder topped up with fluid. It’s better if there are two people when doing it the second way . One person too pump the pedal and keep a eye on the reservoir, while the other person releases the bleed nipple. The art to each of these methods is having a clear pipe on the bleed nipple , so you can see the air bubbles coming out , also making sure the air bubbles don’t get sucked back up on the upward stroke of the brake pedal . If the pedal still feels soft, if you have a proper brake pipe clamp , you could clamp each individual flexy brake pipe to determine where the air might be trapped 2 Quote Link to comment Share on other sites More sharing options...
Arkhangelsk1989 Posted January 11, 2021 Author Share Posted January 11, 2021 Thanks for the help everyone. I will get the garage to have another go at bleeding the brakes and see how It goes from there. The brakes seem too work alright it's just the pedal travel but it passed the mot recently with no problem and have driven thousands of miles with no problems braking. 1 Quote Link to comment Share on other sites More sharing options...

One other thing that could have an effect of a soft brake pedal, if you have rear drum brakes . It could be the rear brakes are out of adjustment. If you pull your handbrake on and the pedal improves , its a good sign the rear brakes need to be looked at or adjusted 2 Quote Link to comment Share on other sites More sharing options...

I converted the drums too st150 discs brakes and calipers on the rear so I think they should be adjusted alright. I will see how I get on with bleeding it but at the end of the day, the brakes are working fine and I haven't had any problems stopping "touch wood".

If you did it yourself, how long did it take you? I did the conversion myself mate. It took me around a days work in total minus the snapped brake pipe because I am heavy handed 😂 Quote Link to comment Share on other sites More sharing options...

Was gonna do front and rear upgrade to 278mm discs. Haha, trust me I was raging at some points because everything seemed to be made of chocolate. Tbh I wouldn't say it has made any difference in braking other than looking better than drums. I suppose upgrading the fronts would benefit more because they do most of the braking. I'm still running standard size on the front but I'm looking too get some better pads as the pagid ones aren't brilliant and my pedal is a tad spongy Quote Link to comment Share on other sites More sharing options...

I noticed that the rear st150 brakes are 253mm and front are 278mm. The kit I found was just for the front wheels, and it doesn’t make sense in buying an upgrade kit with nice callipers when the rear brakes will be smaller with different/standard callipers. https://www.burtonpower.com/hispec-4-pot-road-brake-kit-ford-escort-fiesta-ka-278x24mm-hisk23.html Tbh if I was you I would just upgrade the fronts and put some good discs and pads on. You could do the rear conversion and put some good brakes on aswell but it costs a lot of money too do Quote Link to comment Share on other sites More sharing options...
Arkhangelsk1989 Posted January 11, 2021 Author Share Posted January 11, 2021 18 minutes ago, FiestaForever said: How much dis it cost you to do the back end brake conversion? I got a rear beam for £150 but both wheel bearing were bad so that was another £150, discs, pads and brake hoses were about £100,new handbrake cable was about £30 and a few other things but all together I would say it cost me around £500 but would have been cheaper if things didn't go wrong for me 😂 Quote Link to comment Share on other sites More sharing options...
Arkhangelsk1989 Posted January 12, 2021 Author Share Posted January 12, 2021 14 minutes ago, FiestaForever said: £500 is not a stroll in the park but doable if a person has employment. I saw someone selling just the hubs and brakes as kit without the axle itself, that was more expensive than what you were saying at £150. Might consider doing this when the remaps have been sorted and possibly when cams have been done too. If you need any help then zain on this forum did a step by step on how too do it. He helped me out a lot. I got the axle for a really good price but they probably new that the bearings were knackered and everything so thats why it was cheap. Tbh just collect the parts up gradually so you get decent stuff rather than old worn rubbish like I did. Quote Link to comment Share on other sites More sharing options...

Arkhangelsk1989 Posted January 15, 2021 Author Share Posted January 15, 2021 I know this Is completely out of context but since there are people following this forum I just need a bit of advice. Does my car sound like it's misfiring? There are no codes or anything and it's driving fine with no problem. Cheers Quote Link to comment Share on other sites More sharing options...

Yeah, I think my backbox hasn't sealed on the joint. I used exhaust paste but it's a load of rubbis. I might buy some exhaust wrap and see if that does it.

Arkhangelsk1989 Posted January 18, 2021 Author Share Posted January 18, 2021 Hello, quick update. I have solved the problem. Took it too ford and they powerbled the system on an IDS machine and found loads of air trapped in the ABS Pump. This has solved the problem and now my pedal feels much better and the brakes come on earlier than before. Cheers for all of the help and suggestions 👍🏻 Quote Link to comment Share on other sites More sharing options...

I'm going too cry saying this 😭 £150. Tbh they did a full check of all the braking system and ran a brake roller test so it's peace of mind that my brakes will actually work when I need them the most.

Arkhangelsk1989 Posted January 18, 2021 Author Share Posted January 18, 2021 At the end of the day mine and everyone else's safety is worth more than £150 so I'm happy it's all sorted 👍🏻 Quote Link to comment Share on other sites More sharing options...
