Okay, so I just redid the brakes on my 88 4runner. when I bought it the brakes were terrible, I had to put my foot through the floor to stop. I had the rears done and the I replaced the rotors, calipers(they were both seized) and pads. However I still have no brakes. I can see and hear the calipers work but I get nothing. I am not leaking fluid anywhere, and I bled the brakes twice and there is no air in the lines. What am I missing?!?

 

Master cylinder? Power booster? Are you certain you bled them correctly?

Do you hear a hissing sound when you pedal is depressed? That would indicate a bad booster.

If you've bled the brakes correctly & you are 100% certain of that, it might be a bad master cylinder.

My advice would be to bleed the brakes again & pay extra close attention to how you're doing it & write up exactly what process you followed & what the outcome was (I.E. brake pedal to floor, hissing, black fluid etc.)

 

If you have a LSPV make sure you bleed that last.

 

Did you break them in? New pads/shoes have a break-in period before they grip to thier full potential. After the initial dozen or so 35-0 mph runs, they may still need 50+ more miles to be broke in thoroughly.

About the LSPV, make sure it's adjusted properly as well as bled, if you think it's needed.

 

He'd still have brakes until they were broken in, though.....that is if everything else was working well.

If you pump the brake, does it get better?
If you pump the brake (with vehicle running), hold the pedal, does the pedal slowly drop? If so, it's a bad MC.
When the rear brakes were done, what all exactly was done? It's possible, even if the shoes were replaced, the brake cable may not be moving freely. In that case, start looking at all the moving parts where the cable is run. Make sure they all move freely. Whether or not it's part of your issue, it wouldn't hurt to lubricated everything.

 

Thanks for the input I will bleed them again and listen to what happens.
