Wondering if anyone can help sort out an ongoing problem. I know there may be several factors involved so I will be as descriptive as I can.
At about 170,000 miles and with an MOT suggestion the discs and pads were replaced on my e39 tourer by an independent BMW specialist who services and prepares the car for me.
I have known the owner and used his services for about 10 years without any problems at all. I have always been impressed by how thorough and professional he has been.
The discs and pads were his recommendation, I do not know the make but they could be sourced from GSF.
After about 6,000 miles the slight brake judder became a concern. It slowly developed over this time. I took the car back and the garage fitted new discs under warranty.
It was agreed that he discs had warped.
After a similar period the same thing began to happen again, a slight judder (pulse on the brake pedal) then it got worse to the point of some concern.
The garage inspected the discs and said they were warped. They changed them under warranty once again.
After a similar period it happened again, just as before. Almost unnoticeable to start with after 2000 or so miles getting steadily worse until I took the car back again at about 6000 miles.
Once again it was agreed the discs had warped and they were exchanged under warranty. We discussed correct fitting procedures and practice at the risk of questioning his competence or that of his mechanics.
It was suggested that if it happens again I have the discs skimmed on the car. I asked why this should make a difference saying that if they start fine and then warp then how will skimming on the car help.
Well it has happened again. A little longer this time but it is back.
I know there is no point in returning to the garage, I was impressed that they changed them 4 times so far without asking for anything.
As for my driving - the car is never fully laden and I do not tow with it. Mostly 1 or two people and occasionally my carpentry tools, a door or two and that is all.
Mostly town driving and I am gentle, MPG is more important than MPH to me.
I was taught to gradually apply the brake then release slightly before coming to a stop and then gently apply again. Once stationary apply the hand brake, select neutral and "rest the feet". These habits have stayed with me.
I am not sure what to do next. There is no evidence that returning to the original garage will help. Unless I can determine a reason I have little faith in another garage doing anything different.
Is there an underlying reason do you think? Could the type of pad be a problem, they are the original set from the first disc change. Could it be my driving habits? A fault with the car perhaps?
I am tempted to buy and fit a set of discs and pads myself. I have done this on every other car I have owned with no problems at all and if I had not taken the decision not to "play" with this one I would have done these too.
However I do not think I would do anything any different than the garage would do and so risk repeating the problem without solving the issue.
Well I will turn it over to you. Any advice welcome.
