Rear disc brake problem
#1
Hi I'm having trouble with my rear mechanical disc brake when I pull the brake lever the lever on the brake calliper that pulls up when the pads bite the rotor pulls up but when I release the brake lever on the bars the calliper lever doesn't release and move back down if you know what I mean.....any suggestions ??

1st suggestion: make sure that the cable is free. Disconnect the cable from the brake, and make sure that it moves freely in the housing. If not replace cable and housing, making sure to lubricate the new cable with Triflow or your choice of light oil.

If the cable moves freely in the housing, 2nd suggestion is to make sure that the lever is pivoting freely. 3rd is to check the return spring on the caliper.

The lever pivots freely and the return spring seems fine as I disconnected the cable and moved the lever with my thumb it springs back when released it seems the cable is causing the prob I removed it from the housing and there's some fray on it so ill replace it tomorrow

welcome to the world of disc brakes, glad you have it sorted. It is important not to contaminate the rotors or pads with much more than water and mud. lightly lube moving parts by droplets not spray to help keep things nice and quiet
