No brake fluid to right fron brake!!!!

[pedmonds0219]

Hey everyone, I am having problems with my right front brake that I just installed. I just bought an 97 4runner limited with a lot of miles and a brake problem!!! I would be driving down the road and all the front brakes start seizing to the point where if I let off of the gas pedal the car will roll to a complete stop. I'd pull over and the brakes would be extremely hot, but after they cooled a bit, then I could get her rolling again.

Anyhow, I decided that I should change out the brakes and do the 231mm tundra brake swap on them since they needed replacing anyhow. Well I switched out the calipers and rotors and hooked everything back up, and bleed the right line before I moved on to the next wheel, and I can't get any fluid to the caliper at all. So I called a buddy who was a mechanic over and we started to chase it back to the master cylinder. We chased it back to what he called the "ABS Module" and still have nothing. We tried the front left and it bled just fine, so it is only the right side that is having issues as of right now. :wtf:

Has anyone else experienced this problem as well?

That's weird. Any chance the line to that caliper is pinched of clogged ?
Are you bleeding the wheels in the correct order, including LSPV?
Since you have ABS you have to do things differently, bleed system completely with engine Off, then with engine running, then again with engine Off.

Did you install Remanufactured Calipers? If so, your bad rotor is not drilled right. Replace it with another one.

Sorry to let this sit for so long, but what do you meant the rotor isn't drilled tight? I have remaned calipers.

We finally got the brakes installed and working, it only took 3 hours of bleeding them. But the front right brake still acts up from time to time, I can feel it grabbing once in a while because the vehicle slows much faster when I let off of the throttle than it otherwise would. I can also feel a difference in the pressure I have to put on the brake pedal when it is acting up. I am not sure what the deal is, or how another rotor will fix the issue. For the most part, it works like it should, so I haven't messed with it yet.

If you haven't found the problem yet, check where the flex brake line hose is clamped to the front strut. I have seen several instances where the metal inside the clamp would rust and expand, causing the rubber bushing inside the clamp to compress and pinch the brake line hose closed. When this happens, it acts just like a one-way check valve. The higher pressure generated when depressing the pedal will force fluid past the restriction and apply the brakes, but when you release the pedal, the restriction blocks the flow of fluid back to the MC, and causes the caliper to hold pressure and drag the pads on the rotors. Try releasing the brake hose clamp and see if it helps. If so, then just clean out the built up rust inside the clamp and put it back together.

I had this happen to me on another car. Drivers side hose failed.
Hose looks good from the outside. I took it off and found it was blocked on the inside.

I replaced left and right brake hoses. This solved the issue.
I replaced the good right side hose because it has seen the same duty cycle as the failed left hose.
