WEEDY BACK BRAKES
« on: 29 July 2010, 11:26:45 »
Just changed ALL the brake pads on my 99 3.0 estate. Now, when I brake hard, the front "wanders" in direction, and the rears don't seem to do much.....
Must add, have done enough miles to wear them in a fair bit, and cleaned up the discs well with brake cleaner before fitting pads. No leaks or contamination, and discs within wear tolerances cos checked with micrometer first, or would have replaced discs too.

Any thoughts?

By wandering, does it go left then right or vice versa or does it only pull left, or right.
Hope that makes sense.

If only pulling to one side, I am thinking of a stuck caliper, it can happen when you push the piston back in when fitting pads. Or the slider bit sticking, did you use a bit of anti seize compund on them ?

HTH in some small way  :)

would tend to agree with you Tunnie, but have just changed wishbones,drop arms, and all ball joints!

Front brakes good, but back ones inneffective.

Still stops well..........

How do you know the back brakes are to blame?

I would say take the car out on a quiet road, do a couple of stops from 50-60 MPH and then see how the temperatures of the disks compare (an infra red heat gun is handy for this if you have one available).

If there's a disk that's clearly cooler or cold, there's your problem. If not, look further afield.

If the disks are worn it might take a while for the pads to bed in to the contours left by the previous set. Until then you have a reduced contact area -> less braking.

Just another quick thought, does the estate have a load proportioning valve ? could it be faulty, or disconnected after jacking the car up ?

Did you check inside surface of the front discs before fitting the new pads?

Mine looked ok from the outer surface, so just had new pads fitted, as recommended by the Vx garage.
After a few months I experienced brake judder when braking from speeds above 50mph. Had the front brakes checked again and the inner surface on the front discs were found to be completely corroded, outer looked ok.
So wasted a new set of pads, after having to replace the discs then the pads again. Never took my car back there again.

Know an MOT tester who would do a brake balance check for you?

I assume you haven't hard faced the pads by going out on new pads and braking 'hard' alot? gently gently spanky monkey on new pads for a few miles..
