Front right break pads rattling

Post by combatcarry »

Ever since I bought my used R1100R there has been a very annoying rattle coming from the front right break pad. I changed the fluid hoping that if the system maintained a more consistent pressure (less bleed down) the pads would remain tighter against the disk and the rattle would stop. However, I've changed the fluid and they still rattle. It seems like if I pump the brake lever repeatedly and pull quite hard the rattling will go away for a bit.

Are there any recommendations on what could be causing this? I believe I have plenty of lining thickness (appears to have about 1/4" on the pads). I noticed there are some anti-rattle clips on the pads, but I don't know what they do or how they operate.

Thanks.

In such cases a very small amount of copper grease works wonders. Apart of this how do you identify if the rattling comes from the "right braking pad"? I mean it could also be the discs as the discs are not fixed but floating discs on the R1100R ...

Its definitely the right front outside brake pad. When the bike is on the center stand I can spin the wheel and it will begin rattling. The pad is very loose and never maintains pressure against the disk. I've seen some pads with springs that keep a little pressure on the pad, but I can't see (from the parts break down) that the BMW pads have this.

UPDATE: I think I figured it out. The OEM brake pads have anti-rattle springs. Most after market pads do not. After closer inspection my pads do not have the anti-rattle springs. I'm hoping someone out there might be able to sell me (or give me) an old set of OEM pads so that I can re-use the clips off of them. Otherwise I'm forced to live with the rattle or replace the brakes prematurely.

Seems to be yet another example of an el cheapo aftermarket part not being the best replacement ... I always buy brake parts from Lucas or Brembo and never had any problems. The parts are somewhat cheaper than the original (or OEM) stuff but way better - according to some comparative tests compiled by some of our leading 2-wheel publications.

It seems like a hassle to have to start using the anti rattle parts from your old pads on new ones. Is there an aftermarket pad available that includes these?, what are people using and recommending? the OEM ones are certainly pricey.

As I said, Brembo or Lucas ...

Best regards
