Another Disc & Pad Change Question

Pickled Piper

New member
I read a post on another forum that recommended that a disc and pad change should not be carried out simultaneously. Rather, the discs should first be changed retaining the old pads, then following a certain period of driving the new pads should be fitted. The rationale was based on preventing the pads/ discs from glazing and improving the bedding in procedure. Now, I've changed many pads and discs on several vehicles over the years. I've never come across this advice before. Is it total bunkum, as I suspect? Or is there some merit in using this procedure.

Cheers

PP,

Saw that post as well. My initial reaction was what a good way to generate extra cash for a garage!
 
Total bunkum.

The important thing is making sure that you bed the new pads in correctly. I don't have the information to hand but there are a number of references on the web or Porsche forums on how to do this. It involves warming the brakes up followed by accelerating to a certain speed and then braking sharply to a certan speed and repeating a number of times.

I have done this and my biggest tip is do it very very early one morning (Sunday seems best) when there is no traffic about. You can't do it with other cars on the road.

OK, the consensus is that I consign that piece of advice to the bin.

That's the problem with the internet. Every poster is an expert and there is no easy means of verifying their credibility.

Maurice, sounds like you're making a case for always changing pads and discs at the same time, ie worn pads means new discs as well, and vice versa. ???
