Brakes

[briantheb]

I have a few issues with the brakes which I’ve had my dealer look at but they never seem to solve the problems for any length of time.
At low speeds the front brake surges and feels like it’s grabbing at times or as if the disc is warped !
The reservoir weeps, and the lever has a lot of movement in it till pumped up.
(On these last two the dealer says if the weeping persists then they’ll replace the whole reservoir, they worked in the front brake and for about 5-6 miles the lever was much firmer but then was just as before).
The rear brake is a bit wooden once the effects of any cleaning has worn off and the pads don’t sit right to the edge of the disc and there is now a ridge developing on the disc edge, making wheel replacement difficult !
Anyone else having similar or other brake problems ?

For me - no problems at all (other than the usual observations of the front diving under hard braking and the rear pedal being a bit of a stretch)

I too had a leaking front brake fluid reservoir many months back. Without hesitation, my dealer ordered in a new master cylinder under warranty. The brakes have been fine, ignoring the fact that the rear is pretty ineffective at all but very low speed, and the disks are looking good after 16500 miles.

If you've got a ridge that big on your disk I think you need to replace it! It's normal to get a ridge on the edge of a disk but it should be quite small, maybe 1mm thick at the most. There's a wear limit stamped on the disk to indicate how deep it can be but you'll need a caliper or micrometer to make an accurate measurement; a dealer should be able to advise you.

I had a Triumph Sprint with a front brake that had to be bled regularly or it played up as you're describing. Once bled it was solid as a rock but after a week the lever started coming back to the bars and feeling spongy. There was never any air coming out when I bled it. When I traded it in, the dealer said it's a problem with the master cylinder

I too have an issue with my front brake. A few months ago the reservoir leaked a little bit liquid and i've just turned the srews off the lid a quarter and the leakage has gone since then. Now the brake lever feels sponcy and i can pull it all the way to the throttle. I've an appoinment this friday at the dealer to check out what the problem is. I nonticed the brake fluid is almost black, if i look through the glass of the reservoir. I'm curious how it looks insite.....

Today i´ve been to the dealer to have my front brake serviced. They´ve filled te reservoir with fresh liquid and then they bled the brakelines.
The pressure point is hard now and also the stroke is shorter as it was when the bike was new.
