Rear Brake problem.

[96Cruiser13]

I replaced my rear rotors, calipers, shoes, and pads. When i went to bleed them, there was no fluid getting to them. Theres no fluid at all.. Anyone had this problem? Or have any idea what could be causing it? Front brakes are working great.

your bleeders could be clogged and not allowing fluid to pass. replace (about 3.00 if in stock)it or try removing it and clean it with a welding tip cleaner or other small peice of wire, maybe a bristle from a wire brush. i just replaced mine for the same reason when i rebuilt my calipers it was a result of the PO never replaceing/changeing the brake fluid. remember to flush out the caliber or it may get clogged again.

but theres no pressure or anything? I dont think its the bleeder...

I can hit the brake, and turn the rotor by hand.. Not good

you might just have some air in the line.. try bleeding the leveling valve just in front of the drivers rear tire. or remove one of the rear bleeders and apply a little brake and see if any fluid comes out (don't look to close , and get fluid in your eyes).

haha k..

ill let ya know tomorrow

thanks alot

bled everyting, all 5...
No fluid in the back still, LSPV bled great, no air...
Front bled great also, getting alot of air out

any suggestions on the rear brakes????

I've never had this happen, but one thought would be to disconnect one of the rear calipers from the line and see if fluid comes out of the line. If not try carefully pushing the brake pedal to see if fluid comes out then. You could probably put a clear hose on the end of the the line or use a funnel, etc. to try and catch the fluid (plus a drain pan).

Don't know if you replaced the rear calipers with new Toyota or rebuilt, but I wouldn't assume they are fine. Also look to see if something could have gotten blocked when you attached the line to the caliper.

Did you replace the flexible line between the LSPV and the axle? Did you use anything like teflon tape, etc. on the brake line nuts?

 

[fourtrax]

have to ask, you did remove the little dust (shipping plugs) that came on the calipers before attaching the brake lines?

disconnect line at right caliper apply a little brake check for fluid, re-attach and repeat for left side. if no fluid on either then might have a bad leveling valve. loosen line coming out of valve and apply brake check for fluid to verify you dont have a pinched brake line somewhere.

I'm no help on the tech part as I've never bled my brakes (had a shop do it for me)...but I'm local to you and could lend an extra set of hands if that would help.

Just let me know, I'm not busy for the next two days.

Nope, didnt touch it. The LSPV had VERY clean fluid in it. While the front calipers were nasty as hell. So i flushed them till i had clear fluid coming out, but NOTHING out of the back. I'll keep ya posted.
Thanks for all the help

One more thing that may have been overlooked is that a hard line (steel line) has gotten kinked in the process not allowing fluid to reach rear calipers. A result of this would be that the fluid is backing up at the resevoir.

Do you have any fluid leaking out of the engine bay onto the ground anywhere?

 

[96Cruiser13]

Update:
I took off a rear caliper, so i could disconnect the brake hose. Hit thew brakes with it disconnected, nothing.
Also disconnected the steel line coming from the LSPV, Nothing! WTF!
Any Suggestion???

I never got the MC container even to the minimum line, so i wouldn't think the MC needs to be bled...

Nope, and i checked ALL the steel lines... No kinks

If those front calipers were that nasty, you may have sucked debris into the MC at the outlet. I would briefly disconnect the hard line at the MC and see if fluid flows. If not, you may need to clean the MC.

loosen the supply line going to the LSVP and apply brake see if fuilid come out.. start working your way forward.

did that, started at the back caliper, followed that to the LSPV, nothing... BUT the LSPV bleeds like its brand new...

 

[96Cruiser13]

i guess ill have to bleed the damn MC tomorrow.. Whats the best way? any suggestions?

Clear tubing from outlets back up top? Thats how ive always done it

 

[fourtrax]

ok i'm confused. I thought you said.
"Also disconnected the steel line coming from the LSPV, Nothing! "

is it the input of the LSPV that bleed, and you didn't get anything from the output?
if the lspv bleeds then i doubt it is the MC. if the output of the LSPV is not bleeding then look at the adjustment rod, maybe it is bent or something. disconnect it and move it up and then apply brakes check for fluid, move it down and repeat. i need more info.

 

[96Cruiser13]

Correct.. The LSPV is getting fluid, it bled great... But no output.

Just read through the last couple posts, sorry that was kind of confusing..

I'll try the adjustment rod thing in the morning.. My dad is coming over to lend a hand...
thanks alot
