Well I've got all of the easy part done. Actually the P/O tried to rebuild and the leak appears to be from the e brake actuator. How do I get this thing apart? the only thing left to do is remove the plug, but I didn't want to do it unless I have to.
The piston in this side is stuck in, I tried to pry lightly, but didn't want to put too much pressure on it incase there's something I might break. If anyone has any reference material the Haynes manual glosses right over this. Any help would be apreciated Attached image(s) |

Not sure how to say this. The fluid/hydrolic movement of the piston is isolated from the Ebrake mechincal actuation. There is no fluid where the Ebrake actuator enters the caliper body. The 5mm hex adjuster rotates a shaft that sets the pistion position. There is an o-ring on the shaft where it enters the pistion bore. The o-ring keeps the fluid from leaking out. The Ebrake actuator pushes on the outside end of this shaft, which slides in/out a bit, in turn it pushes the piston against rotor. It also displaces some oil causing the inside piston to clamp as well.
Ok - or is this even more confusing?? Ken |
