Brake bleeding problem, Trying to fix seized caliper(s). (Page 1/1)
72and86 MAY 31, 02:43 PM
I just purchased a project 86 SE V6. It was not running. Engine now running.

Saga continues. Parked for at least a year, probably longer.

Got motor running and not car has no power when test driving. We figured it was the rear brakes are seized up. The ebrake stuck engaged. Brake booster has been replaced and res full. But brake lines won't bleed. Valve is clear on back brake bleeder. Brake pedal is like a brick, travels maybe an inch. Looks like all new SS brake lines throughout. Puzzled.

What condition are your rubber brake hoses in? Are they pinched? Sometimes that can cause issues. Can you take a hose off the caliper and get fluid through it when you press the brake pedal. I would try that one at a time to to see if you are getting good fluid flow in the brakelines. While the hoses are off you could see if the release of pressure in the caliper frees it up enough to remove it.

BTW, If you don't have them Harbor Freight has some nylon brake hose clamps that you could use to seal the line while you've got it off the caliper.

Just to clarify for the OP... Corrosion (and therefore swelling) of the metal clamps that hold the brake hoses in place can cause the hoses to be pinched. This was definitely a problem with the original factory hoses. Not sure if it continued to be an issue with aftermarket replacements or not.

I will check.
