I have a 1988 Toyota Pickup 4WD Manual 22RE.

I replaced the front calipers (drivers side frozen) and pads.

At the same time I replaced both rear wheel cylinders (shoes and drums ok for now).

Before I go any further, I would like to say that the brakes were working fine up to this point except for the caliper problem. The only thing is I let the master cylinder go dry when replacing the calipers. I wasn't paying attention and it all dripped into a bucket.

I tried bleeding the brakes first using the buddy system. It seemed to go well. Then I started the truck and the pedal goes right to the floor. No brakes!!

I tried bleeding the brakes again. Engine off, always filling the master as needed. Again no brakes. Did this three times more. Again, nothing.

Then I went out and got one of those one man brake bleeders. For seven bucks, they seem to work well. Until I start the truck. The pedal goes right to the floor with no brakes.

I am obviously doing something wrong. Could one of the calipers be bad or one of the wheel cylinders? Should I let them gravity feed for a while then try it again?

Any help would be greatly appreciated.

Hell, if anyone lives in the Hudson NH area, I'll gladly buy you a case to show me what I'm doing wrong.

Thanks in advance.

Since you let the reservoir go dry, you will likely have to bench bleed the master cylinder before trying to bleed the rest of the system.

Wonderful.......

Do you know if there would be a right up on something like that?

Found a write up on the net. Seems fairly simple. I'll try it.

Thanks.........

Ditto on the bench bleed. You got air trapped in the MC. That has to be done before you start bleeding at the back of the truck and work your way forward. Don't forget the proportioning valve on passenger side that has a bleed port too. I suggest you buy a master cylinder rebuild kit to get the bleed parts kit. Actually, you can bench bleed the MC while in the truck if you are careful and follow the instructions to the letter. An assistant would be helpful but not mandatory.

Don't forget to do the LSPV last. It usually doesn't take much if the rears are pushing clear, bubble-free fluid.

I honestly don't know where that is, but thanks for the heads up. I will definitely found out more about it and get it done.

Thanks......

The LSPV is above the rear axle, behind the gas tank.

I use a power bleeder (oil extractor from HF) to bleed my brakes. Makes it an easy one man job. Works great, but you need an air compressor to run it.

Thanks for the link. I will do all of this this week.

Back it up onto a hill so the rear is up in the air. This may sound crazy but it worked for me. I did the same for the front to but didn't get any air out of it.

TRY IT, BELIEVE ME. What do you have to lose?
