brakes gone!

[PtypE]

I'm going to try to keep things in order in my mind when i try to explain the whole ordeal. I have a sept 1986 camry dlx 2.0 4 door... So I think its an 87 model...
The other day I did a brake test in a safe area and noticed the brake light came on right before i came to a stop. When i Got home the brake fluid level was just a tiny bit below Max so i toped it off. Then i went out for a drive and my brake pedal went nearly to the floor before the car would slow down and pull to the right.
I assumed a bubble in the brake system, so I bled the brake lines properly and it didnt fix the problem. No noises, or anything. Upon looking closely, with a friend pressing on the brake pedal while the engine is running the brake booster moves forward away from the firewall. I assume the booster has failed.
I replaced the old vacume lines, and looked for leaks, but the fluid level remains full. Before I purchase a new brake booster does anyone else think thats the problem?

its bolted to the firewall with studs and nuts on the inside where the pushrod goes from the pedal into the booster, be sure they are tight, other rhan that a little movement is normal from the firewall flexing

So, then the brake booster could still be bad...

[fredk]

usually if the booster goes the rubber diaphram gets a hole in it and you will hear a hiss when you hit the brakes and or a hard to push brake pedal, a good test for a booster is turn the car off and pust the brakes until the pedal gets stiff, keep your foot on it and start the car and the pedal should drop to normal when the motor starts with no hiss from under the dash, now if you are sitting at a stop with your foot on the pedal and it starts to head to the floor your master cylinder is going out witch is common on these old cars

Ok, so ive ordered the master cylinder and it should be here tomorow, 53$

Brake booster seems fine.

[PtypE]

Ok, so the new master cylinder is working just fine, but I cant seem to bleed the brakes effectively. Is there some sort of trick for Toyota?

If truly Generation 2, i.e., 1987 then: www.camrystuff.com/manuals/gen2/brake.pdf page BR-7.
If 1986: www.camry stuff.com/manuals/gen1/brake.pdf, same area.

Hey guys while we're talking about boosters, I think mine is bad. It takes 3 pumps for the brakes to work right and makes the hissing sound.

Is the replacement pretty straightforward? I've never done anything with brakes other than pads/rotors so advice would be awesome.

[fredk]

its pretty easy, just take the master away from it with the lines still on it

[PtypE]

ok, replaced the master brake cylinder braking restored, now i have a slow leak, also, was curious to see if anyone has heard of yellow/white slime in the oil fill cap...

the slime is pretty common

"also, was curious to see if anyone has heard of yellow/white slime in the oil fill cap..."

Usually this is just condensation caused by a lot of short trip driving.

[disregard]

yeah somtimes i have that yellow slime in my oil fill cap also.

I think its normal because the oil is sloshing around in the engine alot.

[fredk]

yep, seen it before, its from driving short distances or you got coolant getting into the oil
