3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Hello, I have a 95 camry. Brake pedal went to the floor, replaced master cylinder and trying to bleed brakes. Cannot get fluid to L rear or R front. Tried pulling a vacuum still no brakes, thought the new master cylinder was bad so got another one still no brakes. Pull proportioning valve out everything looked ok. Replace wheel cylinder on L rear still no brakes. I do have fluid at R rear and L front. Bled brakes according to instructions from Chilton book.
Did you bleed master after installation? Loosen line fittings, have assistant press brake pedal, tighten line fitting, have assistant release brake pedal. Repeat until no air is coming from line fitting.

One brake problem that occurs sometimes involves the brake hose ... where it couples from the steel brake line to the brake cylinder on each wheel. Occasionally, the hose will collapse, and it will not be visually obvious.... Sometimes they will collapse internally, and not allow the brake fluid to flow. This is more of a problem on older cars. Just to be safe, and insure properly working brakes, it might be a good idea to replace that particular length of brake hose.

Are the symptoms that you are experiencing now the same as what was going on before you switched out the master cylinder?
You mentioned checking the Proportioning Valve. I believe that there is a Load Sensing Proportioning Valve (LSPV - Brake section of the online manual BR-231) on your car as well. Maybe that would be a factor.

Early Camrys split the brakes LF&RR and RF&LR. Your symptoms are tantalizingly similar to that.

Yeah Bled master cylinder before install. Changed out master cylinder because brake pedal went to the floor. Looks like proportioning valve feeds RF LR and RR. So far it's stumped everybody I've talked to. I'll try changing rubber hoses and see if that solves it. Thanks for all your replies, I'll write back when and if I can get it going. Thanks again.
If all else fails, take the master cylinder back and exchange it for a new one. I have seen many parts fail right out of the box in recent years. It may have some kind of internal blockage under pressure. You can bench bleed it and get fluid to flow, but maybe under pressure it will not flow enough fluid. Just a hunch, since all else seems to have failed.
I am having this exact same problem on my 95 Camry LE, 4-wheel disc car. I replaced the master cylinder, thinking that was the problem, I bled the brakes for hours.....plenty of fluid coming out of LF and RR but hardly any coming out of RF and LR. Starting to get to me......
I ended up replacing the brake booster. Brakes bled perfect, have had no problems. That was around three months ago. If you replace booster make sure you get the pushrod set to the right distance.
I replaced the brake booster today and it didn't change a thing. Next i'm gonna take the proportioning valve off and clean it out, if that doesn't fix it, i'm gonna rebuild the original master cylinder with a toyota rebuild kit. I've got a set of goodridge SS brake lines on order so they should help with the overall firmness of the braking system IF I can ever get the current problem figured out.
UPDATE: Today I rebuilt the stock master cylinder with a rebuild kit that I got from the local Toyota dealer ($68.00) and it completely cured all my problems. The rebuilt unit from Oreilly's was no good, all problems are fixed!!

Let me quote myself from my post above:
"If all else fails, take the master cylinder back and exchange it for a new one. I have seen many parts fail right out of the box in recent years. It may have some kind of internal blockage under pressure."
I have seen this happen all too often in recent years. I don't understand what's happening to the auto parts rebuilding industry. Maybe we can help each other by starting some kind of sticky about what brand rebuilt parts are failing.

I ordered a rebuilt master cylinder for my daughter's car a couple days ago. The guy behind the counter could look up the number of master cylinders sold of this type and the number that were returned nationwide. 670 were sold and 16 were returned. He said he typically sees about a 4% return rate and sometimes higher. If he sees a high return rate he steers customers to new units.
