Rear Wheel/brake/something

[Nick Garland]

Hi

I have recently got a new rear wheel (built by tart) Chris King heavy duty ISO. Ive noticed that my magura is also abit weird atm and Im not sure what the problem is.

When riding or just settin gup my bike, I adjust the rear magura so the pads are a nice distance, tpa is fully out (as in on) as I've broken it (new 2005 cant be bodged). Pull brake a few times and the pad rubs on one side, (the slave with the connection from lever). At first I thought the CK needed the axle tightning as it suggests in book. So I did this it was abit lose. Didnt occur for about 5 hours, then it came back. Noticed that on the slave where the TPA has most effect (one without the connection from lever) that the piston goes from like 2cm out (as an example not really 2cm out) to like 1cm out then the other piston goes from no cm out to 1cm out. This causes the pad to rub.

Is this just a problem with the bleed on my mag as I havent bled it since I bought it.

Also does anyone get what im saying? Hard to explain.

Cheers for any help Nick

Basically, the rubbing/shifting across of the slaves is caused by the TPA being constantly on.

If you bleed it like it is, the pistons will be retracted all the way back, and once you've set the brake up, it wont randomly rub any more.

Alternatively, you could just undo the bleed screw a tiny amount, let some fluid drain out carefully, and put the screw back in. The bleed at the moment sounds like it is good, so no worries there.

Oki cheers for that Adam. I will purchase a new lever blade soon then. Unless anyone knows where I can get a 2005 TPA from and how to fit it? As the thread on it has threaded somehow :S
