replace the lines from the front to the rear. Blead them from longest to shortest. have a hard pedle when off. start the truck and the pedle goes to the floor? Any ideas???

 

forgot to mention.....

 

Sounds like you have a leak or air still in there. If not I would suspect the master cylinder is screwed.

 

time to reblead... dont think you got it all....

 

^^I agree.. still air in the lines.

Had the same problem with mine a couple times.

First time, I didn't realize there was a bleeder on the LSPV.

Second time I had a tiny leak between the halves of the front caliper. Replaced the caliper, all better.

 

had that problem on a cady, ends up being if you get air in the ABS block there are pockets in there that you cant get bleeding at home you have to power bleed the ABS block at a dealer, someone that has one anyway. Check your vac line, and make sure you bled in the right sequins.

 

I don't think 86s came with ABS so that wouldn't be an issue. If you've got a LSPV bleed that after bleeding all the brakes.

 

steelhound thank you for your service for our freedom :bigclap: I try to change my brake fluid every 6 months but i have never let it go beyond 1 year

 

I have to blead this too? I didn't do that. I still am confused by why I have preasure on the peddle when turned off...and none when started?

 

Because your breaks have a vacume assist....

you are bleeding with the engine on arent you?

 

I did it off at first and had plenty of stiffness....then i did it while running but never seemed to get any stiffness?

 

I still think you need to bleed it more... with the engine running.. start over... and do do the LSPV as well...

 

I'll try it again this weekend. THANKS!

ps....Congrats on the kid. I have a 2 year old.......that's why I have to wait until the weekend!

 

You think maybe the power brake booster went bad?

 

I doubt it... if it did it would probally feel the same with or without the engine running...

 

I did the powerboost test as described in the haynes repair and it checked ok. ??? That was also my thought.

 

i just had to bleed my brakes this past weekend. i thought i got it all taken care of, only to find that i had to redo it again. after the second time, the lspv was the only thing that still had air in it, and it was amazing how much too. the fluid came out cloudy because of it all.

 

Sounds like a bad brake booster, since it's only "on" when the engine's running.

 

Bleed 'em again, and see where you get.
