The pads on the front caliper have been falling out for the last year or so, but it hasn't been a real issue because the bike they're on wasn't ridden more than a few times a year. Now moved the brakes over to a new build that I expect to be riding more frequently. I did some research today and as it turns out I think I have bent caliper piston pins. I really want to ride the bike a few times before the snow starts, is there any risk involved in riding with bent pins? Over the winter I intend to rebuild the caliper, replace the front brake assembly ($70+shipping) or buy new brakes (front and rear), any advice? Are the pins any stronger on the new Strokers or replacement pistons? Thanks, Bob
bob, i just had a piston pic fail on my stroker that was less than 30 days old. id like to know if a rebuild is something i can perform as well. myself and my lba cannot get ahold of hayes customer/warranty support
edit*
at this point i am so desperate (we are leaving for a 4 day riding/camping trip on november 10th) that i have ordered a replacement caliper and had it shipped "next day air" to me.
hayes does not have customer support Saturdays or Sundays so we will see if they reimburse me for at least the cost of parts. i am not a happy camper right now.
Waltah, a Bruins fan, hmmm, guess I won't hold it against you!! I found a few videos on youtube that went through the rebuild procedure for a set of Hayes down hill breaks, very similar to the trail version. The process looks do-able for the home mechanic, but I'm not going to attempt it till the off season, in case I mess it up (the rebuild kit is on back order right now anyway). My concern is that the process will be a PITA and the pins will just end up bent again. Oh well, $20 s way cheaper than new brakes front and rear.PS. GO WINGS!!!
I had my piston pin bend this summer. I think it was mostly due to me letting the pads wear down too far as the pistons had to push too far out to overcome the wear.
My brakes were over a year old with a good amount of miles.
Hayes sent me a new caliper no questions asked.
Also sent me some new pads.
I've never had any problems dealing with Hayes. They've been great helping me with a few issues over the years.
I did have to bleed the system about 4 times to get all of the air out of the new caliper though.
I just rebuilt an hfx9 caliper. Pretty straight forward. I had bought the caliper knowing the 2 piston pins were broken. Guy crashed pretty bad. But all good now. The bleeding is a pain the first time, but once you get the hang of it its ok. I can assume the stroker caliper is very similar.
