Brake judder and squeal - need the power of PH to solve it
Discussion
The car is a Jaguar XJ Sovereign 2001.
It has been maintained by main dealers up until I bought it last May and by a Jag indie since.
The problem originally was brake judder when braking pressure applied through the pedal was anything other than very light. I took it to the indie where the discs and pads were looking a bit sorry for themselves and so they were replaced. Also there is a suspension or steering component which has a rubber bit which wears out and this was sorted as well on both sides at the front. Sorry I can't recall what it was exactly.
Anyway after this sort out the brake judder was lessened for about two weeks and returned so back to the indie. The front discs had warped in that short time and there was also now quite a lot of brake squeal. So front discs replaced and I chose to get recon calipers on all 4 wheels to cover that angle.
So after 2000 miles the brakes are squealing still and the brake judder is as bad as it ever was.
I'm out of ideas but can the PH collective solve what it could be?

Many juddering brake problems are actually caused by wear/softness somewhere in suspension bushes; it can be difficult to find where the problem lies, unless you just renew the whole set.
On older cars, it can sometimes be corrosion on a mating face somewhere; it's worth putting a dial-gauge on the discs after fitting to ensure there's no run-out.
Unless you've put EBC discs on there, in which case that's the problem!

Agree on this - check the disk runout to see if it's actually warped, make sure the mounting face is good and flat etc. Otherwise have a look at the suspension.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
