I recently changed front pads (Pagid421) which was very easy and I fitted shims and copper greased them. They're now bedded in and are fantastic compared to oem cr@p..!

However, when reversing and braking the N/S pad is obviously moving in the caliper and clunking (only once and again on first application going forwards IYSWIM). Is this likely to settle and if not what can I do to sort it out..?

Cheers,

If it's that much of an issue, you could remove the pad, and weld along the sides... ie, make the backing plate bigger, then grind it down til it's a better fit...... a lot of work for the sake of a clunk though.....

 

Not worth any bother surely?
At least you know what the cause is!

Or just shim out the caliper but don't make the gap so small that you restrict the movement of the pad...

Is it really that much of a problem - do you change direction that much?

 

Cheers guys..

It's nothing worth bothering about, as already said. Sounds worse inside car as you can't really hear it outside.

Out of interest though, I thought that the backing shims were supposed to prevent this..?

As I said originally, I can't believe the difference a good set of pads and hoses has made to the braking. Lol, you also can't believe that these cars are equiped with such crap from the factory..!

 

The backing shims are anti-noise fixes mainly which can be either coated spring steel and / or rubber sheet (sometimes the pads have a rubberised layer applied instead) - they shim out the distance between the pad and the piston, not the pad and the caliper.

The shims are for axial loading whereas the clunks you are getting are due to rotational loading / impacts so one won't do much for the other...

 

Ah..!
