Rear brake caliper mystery?
Got a weird problem with the rear offside brake unit on my 2002, 156.
I replaced both sets of discs and pads a couple of years ago as per norm, then whilst I was driving the car maybe 12 months later started to get the dreaded squeeling noise coming from the rear.
On inspection of the rear brake discs/pads the nearside was low and the disc fine, however the offside was nearly down to the metal with the innerside of the disc slightly scoured.
I duly replaced the pads only as I did not have the time and money at the time to replace the discs as well.(also serviced both calipers).
I have since checked the pads for wear as the squeeling noise is still present to find that the nearside is still ok with plenty of meat left on it whilst the offside has worn twice as much.
Initially thinking that the problem lay with the caliper with it possibly sticking on, I had it replaced with a 2nd hand unit, I got the technician to look at the wheel station before he changed it and he said the wheel spun freely and so the caliper in his opinion did not need replacing, for peace of mind I got him to replace it anyway.
The squeeling has returned with further excessive wear on the offside pads?
Am I missing something?
The only other thing I can think of, is if there is some sort of apportioning valve in-line with the brake line to the offside rear wheel station that is playing up?
Hope there is some guru out there that can shine some light on this weird problem.
