Brake bleeder

Not the best idea to force all of that old corroded fluid back through a system. When doing a brake job on a daily driver don't push the caliper piston back without opening the bleeder or you're pushing the crud back into the ABS and the MC.

I agree.
Not a smart idea to push the crud back upstream.
If it has older fluid I like to flush the lines and calipers by this method:


* Disconnect the brake hose from the caliper
* Disconnect the hard line from the master cylinder
* Push clean fluid thru the hard lines
* Push clean fluid thru the calipers ( in reverse)

Then reconnect and bleed the system


When I back flushed my Strange Brakes caliper a bunch of black pieces came out. Now I know why the calipers are dragging. I think the piston seals are wasted
