Title: Picture of the brake piston. Decent or junk?
Post by: Jenya on March 23, 2009, 10:21:08 PM
Hi,

I was wondering if this amount of pitting on the brake piston surface is acceptable or warrants the need for a new piston set.

Thanks,

That's fine.  Clean it up with a Scotch Brite pad.

Inspect the inside of the caliper bore for corrosion.  If it is about the same, Scotch Brite it too and reassemble.

I am talking, of course, mainly of the deepest pit in the middle of the picture that will be in contact with the rubber seal.
Wonder whether it might allow a leak, though I haven't had a leak yet.

I do intend to replace the rubber seal though.

The pitting on the end of the piston doesn't concern me much.

Is it still okay to use?

I wouldn't sweat it.  But then again there is only one way to find out if it is going to leak.

Spring for a new one: $22.53 on bikebandit.com
