Has anyone rebuilt their calipers? i'm looking to do this but i can't find out the size of the seals I need, and i'm not dropping $30 a caliper for an entire rebuild kit online

 

Bike bandit sells oem seals separately. I'm looking and it looks like they are about $5 a seal

 

Good to know. I've been wanting to rebuild the brakes on mine, but I haven't a clue as to what seals I need.

 

Pretty much its just piston seals and dust seals for each piston. Really though unless they are leaking or the dust seal is ripped they don't need messed with. If they are sticking it's usually corrosion on the piston which sometimes can be cleaned up with real fine sandpaper and brake cleaner.

 

+1 to Ben.

Most critical to a brake over-haul is smooth, polished hanger-pins,
and freshly grease packed boots.

A quick polish on the pistons is usually plenty of attention,
short of having a weeping seal.

If you really want bang-for-the-buck, upgrade to SS lines,
while you're massaging the system.

So i figuered out the size was 27mm for the seals...
I was planning on taking out the pistons for a good polish but I making sure that if something was to break i'd rather have the replacements right at hand, and since this is my only vehichle at the moment i'd rather get it done right.
The bike actually came with SS brake lines in the front too when i bought it, score!
