Front Brakes Dragging, wheels don't spin free Options

[7TPorsh]

Tried looking in search...

I changed out the following;
- Front brake rotors
- Front bearings and seals
- Front pads

I tried to push back the piston enough to get the pads in...ending up tapping them in but not too much effort. I noticed that it was tight. Thinking it will loosen up, i finished the job.

I get the car on the ground and out on the road a little and realize that the car just doesn't roll...i am working against the brakes. Brakes didn't 'adjust" and are still really tight. Lock nut is not overly tightened.

Are the clearance clips in place on the pistons? They automatically set the clearance on the front. Rears have a screwin vent clearance

(IMG:style_emoticons/default/huh.gif) (those are piston positioning clips meant to keep them at 20 degrees)

Gary, check the softlines. They swell internally with age. This allows pressurized (by your foot) fluid to go by and only slowly leak back into the MC/res. location. You can tell if the car rolls after it sits for a while.

Your description "ending up tapping them in" usually means the pistons are coked with brake fluid schellac. It's a combo of gummed up fluid and rust on the piston walls. the only way I know to get that fixed is to rebuild them. All of it will come off with a polishing wheel or a vibratory polisher (usually).

Check the pedal as George suggests. I have had this happen a couple of times but, you can feel it and, you can diagnose by pulling the pedal back with your toe. If you have to/can do that then it's you pedal bushings.

Good luck.

Eric -are you saying the hose(s) actually get a buildup and act like an orifice? (ok going in but slow releasing?)
