Hi

I have a 2004 reg Mondeo 2.0 TDi which has developed a judder which I can feel both when cruising along the motorway (50+ mph) and also when braking (any speed). At first I changed the front brake pads which reduced the severity of the issue considerably but didn`t completely solve it. Next the rear pads got changed, slight judder still there. Finally I`ve had the wheels rebalanced but still the judder is there.

Some other info:
I didn`t change the pads cos thay all looked nearly new.
All the wheels and tyres are brand new. I bought new alloys after the orginal ones corroded leading to rim leaks and constant slow punctures :(
The car has another issue of pulling to the left but I know that is down to a misalligned rear toe adjustment arm (see my other post).
I did ask Quik Fit to rebalance all the wheels but I`m fairly sure they only did the fronts.

I`m quite happy to tackle any task on the car, have built kit car in the past and have a garage full of tools :) So avoiding high garage costs would be nice but if it needs specialist tools then I`ll have to fork out :(

Some Questions:
If its not the pads or the wheels, what else could it be?
How do I check "washout" on the new pads and how do you adjust it?

Any other thoughts / ideas?

Any help much appreciated.

First thing i would check is that all bushes all ball joints are ok, then i would change the front disc's that the most common problem, if you feel it when your not braking there also could be a sticky caliper (how were they when you changed the pads?) giving the continuess shudder and would explain a warpped disc i would not think it was a back brake problem unless you feel the shudder it in your seat.

front Ball joint/bushes
front disc/calipers

not special tools required for front brake disc removal
if you need to change the caliper your will need to clamp for flexi hose and you will need to re bleed the new caliper

also a pull to the left could also indicate a siezed caliper, does it pull worse when braking??

I've recently bought an 05 plate tdci and had the same problem, i had a new set of tyres fitted (pirelli P6000's), all wheels balanced and the tracking/4 wheel alignment adjusted and it's cured the problem, she feels like new now and i'm a happy camper again, not anything you can do at home but relatively cheap (apart from the tyres) and easily done by any good tyre company, so i'd avoid kwik fit, they ballsed my last cars tracking up and caused it to rub out a new set of firestones in just over 6000 miles (had no problems with the previous set, they done about 25k), hope this helps
