Brakes

#1 Post by Rover dave » Sun May 10, 2020 4:50 pm

I have a problem when braking on my car , every time I apply the brakes when slowing down from 50ish to 30ish the steering wheel vibrates . This started awhile back so I got brand new discs new brake pads cleaned the calliper` s , pistons , . Yesterday I took my alloys off put back on my basic steel wheels exactly the same problem :mad . I have checked all the bushes , drop links suspension parts , I cant see any wear , damage or anything out of place wheels were balanced a short time ago . Any ideas ? :S ( Rover 214si 1993)

Lift front of the car on a jack so the tyres are just off the ground. Go to the wheel and holding it at 9&3 wiggle it from side to side and feel for any play. Then try 12&6.

If any play (firstly it’s an mot fail) secondly it’s likely to be a wheel bearing issue. There is something knocking your discs out of true.

If not the bearing I’d consider swapping the discs again.

When I had this problem and changed the discs, the old ones had localised pitting which looked very like impurities or inclusions in the metal.

The front end of an R8 ( and R3s and 800's for that matter) is prone to brake disc run-out induced brake judder.

To minimise this you need to us a DTI when fitting new discs. Fit the disc to the hub, secure with nuts so it's not loose, zero the DTI on a track about 1/2" in from the outer edge of the disc then rotate the disc 360deg and record the maximum run-out.

Do this in the other 3 possible positions and choose the lowest to fit the disc to the hub.

Obviously this is in addition to making sure all the other parts and joints are in good nick.
I like Twin Cams.... and Single Cams

Also fitting cheap parts ie discs is another issue they warp , made of cheep steel . You get what you pay for and brakes and tyres keep you one the road .
Recomissioning a 214 at the moment with 30k on i brought last year and the discs are not even rusty and thats before i clean them up ( picture attached ) its not been on the road since 2002 quality lasts .

I find putting alot of picture on here a pain but will try ,the discs on yours could be 238mm. Insteaded of 262mm so i would check first , 238 cant be upgraded with the 262 mm .
