Hello friends

I am remote in northern Norway right now and its not easy to get professional help here. I had a flat rear tyre yesterday but managed to get that fixed.
The problem now when I have put back the wheel on is that the rear brakes hardly works at all. The rear brake lever "bottoms" when braking but theres just a little of braking happening. All the mechanical parts seems to be where they should and the brakes are working, just way to little. What could could be the problem?

I have tried to see if it was air in the system and aired out a little but it didnt get better......any suggestiones?

Thanks in advance!

Did you make sure there is a brake pad on either side of the disc and they haven't been pushed together.

Believe it or not I've seen this done before.

Also check that there is no dirt or grease on either the pads or disc. It can be easily done when trying to hold everything in place to line things up.

It is quite easy to dislodge one of the pads out of its retaining groove in the caliper bracket (particularly the non-piston side) when refitting the wheel, especially if you have used a lever to get the pads apart. Check both are located properly in their respective slots.

Another thing that's happened to me (not on the XT mind) is that, when sliding the disc between the pads, one of the friction surfaces has broken away from its backing and fallen off, where the bonding has failed! Have you still got both friction surfaces still?

Thanks so much for answers. I have found out what were wrong. One of the brake pads were slightly bent out of shape and the brake pad was not in the track/slot. A little of the friction surface had also loosened and partly felt off.
But I have been able to bend the brake pad back in reasonable position and its working ok now. But it will need replacement when back in a garage.....
