bikespace Posted February 4, 2005 Report Share Posted February 4, 2005 Just spent an evening with Doughbouy stripping ......his brakes, as they were binding. It became apparent that the side furthest away from the fork leg was not retracting fully after braking. When we got it all off, it did take some pushing back with g clamps - this was even with the calipers split in half, so no hydraulic pressure. What's the norm with these? Anything you can do once they seize (a little). Left in a WD40 bath for about the time it takes to drink a beer, it does seem to have freed up a bit, but is still binding. You can see when you release the brake that one side is retracting, the other stays pushed up against the disc more. Anything that can be done? Awkward to try and free it up at all when it's stripped down as you need hydraulic pressure to get it out again. And one last thing, can you buy the calipers in bits? Or is it the full job?

the artist formerly known as ish Posted February 4, 2005 Report Share Posted February 4, 2005 Put it in a vice and put a peice of wood against the puck, then blow it out with air, make sure you use just enough, don't go sticking the air hose in and giving it full whack. See if there is any marks on the puck and lightly sand them off with fine paper, the seal should be able to compensate for the bit you take off. Or take all the empties back and buy a new bugger Quote Link to comment Share on other sites More sharing options...
marky g Posted February 5, 2005 Report Share Posted February 5, 2005 Been here before with road bikes BS, 99% of time you will have to strip down and pull the seals out.......get your self a very small flat screwdriver or even better a dentist's pick and clean out the recess the seal sits in, WD 40 will help as a cleaning solvent. replace seals with new and you will be away. The problem lies with the alloy body which the seal sits in, the alloy starts to rot under the seal pushing the seal against the piston and making it even harder for it to work properly...........

bob Posted February 5, 2005 Report Share Posted February 5, 2005 I agree, you probably will have to strip the calliper down, but i once had this problem and after taking the whole thing apart it turned out that one side was actually meant to go back further than the other for some reason.

bikespace Posted February 5, 2005 Author Report Share Posted February 5, 2005 (edited) Right, cheers all, looks like caliper off again. We had the caliper stripped, but couldn't get the piston out of this side, and didn't want to force it. Right Doughbouy - something for you to get on with when we get back from the pub Prediction for the six nations: Deleted due to complete misery I'll have to remember to edit this later. I predicted Scotland to beat France, but they were robbed! Edited February 5, 2005 by bikespace Quote Link to comment Share on other sites More sharing options...
