91 S-10 Breaks!!! HELP

readajust the back shoes

po> Now i know my s-10's , i know every thing about them... now im stuck.. i

Try the power booster, mine did that before and I replaced everything but the booster.

Power booster failure will cause a HARD pedal d/t lack of vacuum assistance: the exact opposite of what he is describing.

Doc

You obviously don't know about them or you wouldn't be here.

My guesses:

1. Rear shoes set too loose.
2. Small leak in one of your new brake lines. Flare fittings can be a real bear at times.
3. Proportioning valve is FUBAR.
4. Internal leak in new master cylinder or ABS hydraulic unit if equipped
5. Master Cylinder not bench bled

My question to you is, WHEN did the pedal go all to hell on ya? Before you started, midway thru the work, or after the last step?

Doc

Remove the breaks, and install brakes.

yeah DOC! i do know every thing about it,, and i did all that shit,, i bypassed the abs, and ran new lines to the back it had to be bleed more.. DOC!

What about the proportioning valve? Is your truck equipped with one?

Doc

1.Why did you bypass the ABS? 2.Did you bench bleed the Master Cylinder? 3.Did you let the rears gravity bleed? Charles

get two long jawed set of vice grips, put some rubber hose over the jaws and crimp off both sets of rear brake lines (the rubber parts of course) to isolate the problem to either the front or back brakes.

Now try the brakes and see if the pedal is better

or just unscrew the brake lines at the master cylinder and put two finishing nails in the end of the connector, put them back on and the will cut the rears completely off. Just make sure to remove the nails before you drive it.

I dont reccomend anyone doing this for an extended period of time, I was just on the side of a country road in the middle of BFE and had to rig it to get me to town.
