brake pad springs

Postby mattl80 » Mon Feb 11, 2013 23:31 pm

Just an observation really. The springs that hold my SLX brake pads apart look so fragile, im amazed that these things actually work. The tolerance is so tight in terms of the whole system.

Has anyone ever needed to replace them/ had there breaks not retract properly becuase of dodgy springs? I dont really understand how they work as well as they do!

they dont "really" hold them apart they just reduce the rattling on the pistons.

the spring has nothing to do with piston retraction.

that is the piston seal.

so once they have been pushed against the disk by the pistons, how do they return to the default position? i thought it was the springs that "sprang" them back, away from the rotar?

the seals moving. remove the spring and the pads and wonder in the movement in and out.

You can run the brakes without the springs. I was having trouble with squeaking Avid pads and I experimented with no spring to see if it made any difference. It didnt but didnt have any affect on the brakes. You get a new spring with a new set of pads so dont worry if you bust them.

It's sort of like drinking wine through a straw. Sort of.
