315 Grimeca Front Brake

Featured Replies

My friend has a 315 with the front grimeca brake and one of the pistons is seized in the caliper.

Can someone tell me were I can get spares from? All the places are we have called are out of stock and some even say they spare parts are no longer avalable!

Cheers,

Lennie.

I may be wrong here but if the piston is properly seized then you'll need to replace the caliper as the bore 'should' be damaged - in which case you could fit a 'new' caliper. Chances are though that the caliper needs a clean.

We do this fairly regularly on our mountain bikesby blowing out the piston with compressed air, cleaning the bore/piston/seals and reassembling with brake grease lubricating the piston.

Like I said, I could be wrong but this is defo what I'd do first... you've got nothing to lose.

Good info thanks, i still need to know who can sell the parts though, they are the big problem.

My monty had the single piston caliper whick i changed to a twin pot ajp unit from off road moto in blyth Northumberland think it cost about

My single pot grips like a scorned woman holding your testicles, is the twin pot really that much of an advantage?

My twin pot made a huge improvement as the single pot was weak at best but I think its age was starting to show

Best cash Ive spent in a while but I dont think the boss would agree, thats why I hide all bike receipts!! :lol:
