Reply To: bleeding Tektro m285 brakes (why is there a pin hole?)


Yea the sponginess comes back after the ride, when the bike sits.

So the debris in the master cylinder can cause this?

Guess i’ll be cleaning that this evening.  would this need to be completely disassembled? or could a simple clean by pushing the cylinders out a bit. ( just wiping the cylinder with alcohol and re-lubing.)
