Title: New Brake Caliper Wont't Release
Post by: DnStClr on May 21, 2007, 12:30:14 pm
87 Scottsdale R10-Front brakes-
I've installed both new Brake calipers and a hose on drivers side. Trying to bleed the system hasn't gone well. There was a LOT of dirt in the reservoir before I started. I syphoned as much out as I could. During bleeding, there's very little fluid and no air bubbles at the bleeder on the passenger side.   
The drivers side seemed to bleed ok. The problem is- the passenger side rotor is being held tight  and the brake pedal has too much travel. Is it possible the passenger side brake hose is collapsed or plugged, or could it be air still in the lines somewhere?

I just had this same problem I got a bad caliper. Brake the brake line loose at the caliper see if any fluid comes out.

I also had this problem and it turned out to be the brake hose.It looked fine but had came apart on the inside and would not let the fluid drain back causing the calipar not to release.

My money's on a clogged hose. They're cheap and it's best to replace them in pairs anyway.

It was a bad hose I guess, altho ya can't tell by looking at it. when I took the old hose fitting off the caliper, the brake freed up. New brake hose installed now. So with 2 new calipers and hoses I should be good for awhile. But after bleeding them I have mushy brakes. I'll try to bleed them again tomorrow. Off to work again for today. If it's not that, it's dr.'s appointments or Krogering. A guy can't find time for anything. :)

Try cleaning and adjusting th rear brakes and then bleed them from back to front working farther to closer to the master.
