Today i went riding with about 14 other guys when i noticed my bike felt like it was be drug down(couldn't accelerate at quick and hard to get going from a stop) so when i come to a stop i tried to roll forward and realized my rear breaks were completely locked up and barely allowing the tire to move. Then on the way home my front break pressure was almost completely gone for about 5 min then suddenly came back for 2 stops and then dissapeared again. I think front breaks just need to be bleed, how ever wtf is with the rear anyideas?

 

Just take apart the rear caliper and rebuild it. It's probably the piston is getting stuck. Easy to do and parts are cheep.

 

yep, what he said. and rear brake master cylinder rebuild too. same exact thing happened to mine.

 

did you use the rear brake at all during the ride?

 

yea i use both brakes when riding but my guess is air in the front brake lines? and second i know they use to sell caliper rebuild kits do they still do that and if so where? or do u just buy part by part oem? and if so what parts do i need

 

i find ronayers.com is cheapest for OEM parts.... the fiche is somewhat easy to understand if you know what you're looking for. as far as the rear, it *might* only need a piston cleaning. it could have just gotten stuck if you haven't cleaned it and it had some build-up on it.

not sure how old your brake fluid is, but it's possible you could have boiled it... i guess. if it was only dot3 and it is a few years old... it depends on how hot you got the front brakes and how low the boiling point became... (that could have caused the front brakes).


if you don't feel like rebuilding your calipers, i'd at least give the pistons a good cleaning.... but if you'e going to bleed them, you may as well take them all the way apart, replace seals, and clean them

 

Partzilla seems to be cheaper. BUT, you might not get the best service. I'll be posting a review on my last order. I think since they changed name, they went downhill.
