Hi everyone, 

 

I have possibly a very dumb question. 

When I converted my car to discs from drums, I used a secondhand disc setup. I replaced the ball joints, wheel bearings, pads, and CV joints, but I retained the discs that were provided as they were thicker than the minimum thickness. Since then, I purchased new discs from Minispares, and this past weekend I decided to fit the new discs. 

 

The pads had closed up to the old disc, so when I fitted the new discs, I needed to force the caliper over the discs by lightly tapping the caliper with a rubber mallet. 

 

I was wondering how long the pads would rub against the discs and after roughly how many kilometres of driving the rubbing sounds would subside? Generally, noises coming from the wheels and suspension make me very uncomfortable. 

 

Thanks for the assistance. 

 

Regards,

 

Vinay

impossible to say as they will need to wear to fit. but you should have pressed the pistons home first. rather than forcing the calipers to fit.

I tried this. I wasn't too sure how to do it though. The pistons didn't budge.

Why not read the manual, its not like its a safety critical item or anything.

use a G clamp or somthing, keep an eye on the fluid level as it may overflow so you might need to remove some. push the pistons back as far as they can go.

Please refrain from acronyms with swearing involved, and just because it's obvious to you doesn't mean you need to be rude!!

Your pistons might be fecked and rusty hence not being able to be pushed back in.

Possible, but they're about a year old, stainless steel ones from MS and probably less than 5k km old.

If the discs and pads have been left to go too thin then stainless or not a layer of crud builds up on the piston as it becomes exposed beyond the rubber gaitor, push it in and hey presto either a leaking seal or a jammed piston!
