Question about 2001 Toyota Camry

1 Answer

Brakes have been relined and bled. New master cylinder and powerbooster. I have checked the vacuum to the powerbooster and it registers 50 lbs. Pull vacuum on booster and it holds vacuum, until pedal is depressed. When I pulled a vacuum on the booster, manually, brake holds. Turn on engine and there does not appear to be any booster as the peddle drops. Any ideas?

    Turned out to be a bad master cylinder. Got two bad rebuilt master cylinders from parts place. Got a new one (not rebuilt) and the brakes are great. The vacuum valve is OK. Thanks for input.

Usually there is a valve on the vacuum line to hold vacuum in the booster, check this valve

1968 coronet.new drums,master cylinder,lines,pads,2 boosters. Completely bled, push rod proper length,pads adjusted. Still just manual brakes.


I know that when the engine is shut off, after one or two pumps you lose the power on brakes. Your problem has something to do with the engine vacuum that works in coordination with the master cylinder. Check out the vacuum system and/or connections involved.

Install new brake pads and rotors all 4 wheels. Replaced front 2 calipers. Bled brakes. New clean fluid coming out. pedal is still soft and goes to floor. 200 Seebring.


Are you losing any Brake Fluid? Is it visible anywhere at the four wheels? Is it visible anywhere else?
The Master Cylinder may be defective. When you bled the Brakes did you maintain proper Brake Fluid Level in the Master Cylinder? If you didn't: and air entered into the Master Cylinder there maybe air within in the system in the Master Cylinder. You can bleed the Master Cylinder by removing the brake lines, adding more fluid, pumping the brakes, bleeding the air out of the system.
Are you losing Brake Fluid and can't find a noticeable leak? Then there is a good posibility that the rear seal in the Master Cylinder is leaking and the Fluid is going into the Brake Booster - which is the large wheel shaped drum located on the fire wall. In this case both the Brake Booster and the Master Cylinder will have to be removed and replaced. The Booster contains seals that Brake Fluid is very caustic to and will ruin these seals- causing future failures.
If no Brake Fluid is lost, no leak found: Check the Brake Booster Vacuum Advance. This should be connected to the outside of the Booster, attached to a hose, with the hose going to the engine. Check to see if this is working properly. Replace if needed.

Just replaced master cylinder on 1990 aerostar and bled the brakes, still the pedal goes to floor and i have no brakes


Did you bench bleed the master cyl. before installing it? then when you installed the new master, did you bleed all 4 points? If yes, then check all for points for leaking caliper/s and leaking wheel cylinder/s. If the van has ABS, check the valve body for a bleeder screw and see if air bleeds out of it. If you've checked everything twice and did everything right then your new master cyl. may be defective.

Changed caliper on 2005 ford freestar and now brakes are spongie.


Use a vacuum pump brake bleeder starting at the furthest point from the master cylinder. They cost abt $35. Be sure to keep master cylinder full... :)
