Post subject:  Brake pad anti-rattle springs
Hi guys,
Does anybody know a stockist of 7.5" disc pad anti-rattle springs for a Cooper S? I haven't got them on my car and I sometimes hear them 'tink,tink,tinking" as I drive. A tap on the brake pedal seems to stop it so I think springs are what I need.

Best regards
Al

You can make them out of milo tin by finding an old second hand one and using it as a template. AFAIK they are no longer available....

Alternative I think is to put some silicon based brake compound on the back of the pad where it touches the piston like in some modern cars.

Hi Lillee,
I don't have a pattern unfortunately! It is possible that springs from something else will do the job, someone might know what??

The compound on the pad is usually to stop squeal and I doubt it will help the problem I have.

The compound (Although I have limited knowledge cept that I used some on my commodore few years back) makes the pad stick to the piston, therefor elimating movement and rattle. But like I said, don't quote me on that one! :oops:

Hi Lillee,
Hmmm, that might work, I never thought of it working that way. Have you any idea who's product it was?

Unlike the 8.4" discs, Cooper S 7.5s never had anti-rattle springs.
The pins just go straight thru the pads. 998 Cooper was the same setup.
They did have anti-squeal shims, but as said these are rocking horse now.

I believe this is caused by disc "run-out". The factory manual specifies the limit (can't remember it off the top of my head). Can be checked with a dial guage and reduced/eliminated sometimes by repositioning the disc/flange assembly on the CV spline, or replacing the flange if worn inside. Repositioning the disc to eliminate run out is a frustrating, time consuming exercise (a C o a Job), so it may be easier to just turn the stereo up :wink:

Hi Pete,
The discs (and pads) are new and running within a couple of thou. The frustrating thing is they never did it with the old discs which weren't true! The problem is minor, I agree but I felt that the original shims may well have had a dual function, holding the pads steady as well as reducing squeal. I can probably make something to do the job. Thanks for your thoughts.

Hi Al,

It's a common product, I would ask your local Repco or Autopro. I know that most garages will use this type of product when doing brake pads...

Yep. From memory they're made from a thin springy type material. Brake specialists might also be worth a shot. :idea:

Guys, It looks like your talkinig about 2 seperate things (as Doc mentioned)
There are anti-squeel shims (I have some, old, can be used as a template if you want (soon as I find them)

The other part is the Spring that sits across the two pads... retaining spring.
Ive never seen one, dont think they came on 7.5" disks (cooper) and are generally not needed... thats whats causing the tink tink I believe.

Hi Peter,
I acknowledged the purpose of the shims a few posts ago and I said I thought they may help hold the pads steady. I've not seen one, so I don't know but I am aware that anti-rattle springs usually fit on top of the pads. Thanks for pointing out the possible confusion mate.

you surely do need them. A previous car I had had the springs and I also followed the opinion that they were no necessary, that was until the pad material seperated from the backing plate. The cause was the pad rattling around had weakened the back of the friction material.

You really dont want that to happen at speed.

You can get larger ones and then cut them down and then curl the ends so they all fit. Thats what I do to great effect and never had a problem.

I had this issue with my lancer, the clip got damaged and I am running without one. It makes a light rattle sound when going over bumps, and very rarely when I pull up, I get a low vibration noise like a truck.

Asked a couple of shops and no-one can get them, some pads may come with them - put can't find any.... And this is for a lancer, on the rear so I don't care too much - good luck on the mini!

FYI I don't run anything on my car, but I have relatively new pads (less space for them to rattle)...
