Boswell Posted June 18, 2007 Report Share Posted June 18, 2007 (edited) Maybe you have set your pistons up too far away from the rim. Edited June 18, 2007 by mr ? Quote Link to comment Share on other sites More sharing options...

El Cristoff Posted June 18, 2007 Report Share Posted June 18, 2007 white spirt the rim, get all the crap off the rim, file to new material on pads, regring, tar, sorted Quote Link to comment Share on other sites More sharing options...
Grant H Posted June 18, 2007 Report Share Posted June 18, 2007 white spirt the rim, get all the crap off the rim, file to new material on pads, regring, tar, sorted you dont need tar.if he's just put a new grind on it doesnt need cleaning.just thought, maybe the pads need to be bed in some more? how long have you riden on them?

Krisboats Posted June 18, 2007 Report Share Posted June 18, 2007 i know its sounds stupid but how many grinds has that rim had?my bmf went all shitty after the last time i ground it..Please tell me you weren't trying to imply that the brake gets worse after your rims been ground a few times. Thats just retarded.I think the solution is pretty clear. Get some sandpaper and just take the edge off your grind a bit. I'll bet you've given a nice beasty deep grind... which can give a good hold, but get some force behind it and it'll shave material off your pads rather than letting them grip. Sandpaper the edge off, only needs a little rub all the way round the rim and i'm pretty sure you'll find your pads get their act together.

max-t Posted June 18, 2007 Report Share Posted June 18, 2007 set the pads up square to the rimmake sure they both hit the rim at the same timeset them up as close as possible without them rubbingmake sure they are clean and worn straitadjust the tpa all the way off so that the pads are sitting as far into the slave cylinder as possible.grind the rim in the same direction on both sides (anticlockwise) Quote Link to comment Share on other sites More sharing options...

Thats just retarded.no, i was trying to say that my bmf was flexing over and making my brake shit because it had too many grinds. Quote Link to comment Share on other sites More sharing options...
bousfield19 Posted June 18, 2007 Author Report Share Posted June 18, 2007 well doing the regrind and sanding the new pads as well as the water bleed has made a load of difference. The rear brake is really grippy now . thanks for all the help.I have just had a nice ride with a couple of mates and my god im aching all over serves me right for not riding for 3 years Quote Link to comment Share on other sites More sharing options...

mitchy-boy123 Posted June 19, 2007 Report Share Posted June 19, 2007 I would not listen to them all you need to do really is clean down your rim and use a bit of tar making sure you spread it the whole way round your rim then it should be fine lol.from mitch.

BRISA RIDER! Posted June 19, 2007 Report Share Posted June 19, 2007 Iv seen loads of lads do that. they buy new pads then wack them on a tard rim, the first big gap they do they end up taking chunks out there pads! simply because the pad compound needs to bed in!!!! .DANNY MACASKIL IS A GOD.
