You might have got a defective master cylinder. I got two in a row once, boy did I go thru brake fluid, until I went and got another brand, then plenty of pedal.

Check the rubber break hoses going to your wheel cylinders, one or more may have broken down and are expanding when you apply you breaks.

You must have air trapped in the system still, dont drive this car until this problem is fixed, please, for safety reasons. if you dont know how to bleed the brakes have a professional do the work. the fluid might have been contaminated and should be totally reserviced, DOT 3 fluid or better.
can you rate this!

Do you have to remove brake lines when you change the brake booster


Check rear of Master Cylinder--If wet likely Master Cylinder Leaking and Booster Damaged. They Should be replaced as a mated pair. (for warranty) and brake lines removed and system bled.

2001 Silverado 2500 HD Why Rear brakes don't work after I installed new hydro-boost power booster, master cylinder, calipers, and pads. I bled master cylinder before installing, and brakes beginn


Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

Toyota 4 runner brake booster noise


if you can see brake fluid around the booster then yes it is most definitely not right, but sometimes these can fail without any fluid noticable, the visible fluid could mean that the brake master cylinder is failing & this will have an adverse affect on the booster power & performance, check your brake master cylinder first as this is a much simpler & easier repair than the brake booster & can be done at home on a flat drive or or street even, a Haynes manual is invaluable for the home mechanic & i recommend you get one as soon as you can as this will help you diagnose the problems with your vehicle before going to a mechanic/garage, if it is the brake booster at fault then i suggest you go to your local scrapper/breakers yard armed with tools & the Haynes/Chilton's Manual (Depending on which side of the pond you are from) & remove the brake booster from a now deceased Toyota 4Runner & remove the brake booster & master cylinder in one should only cost you a few Quid or Bucks & replace the part once your vehicle is back at home, once the parts have been replaced the brake system will need to be bled so that there is no air in the brake lines, this can be easily done with two people at home, Jack up one corner, remove that wheel & then just crack off the bleed nipple of the brake line Putting a bit of clear hose over the nipple to catch the excess brake fluid in a jug etc & have a friend push down slowly on the pedal, when only fluid comes out with no air then the system is bled for that wheel, Check the level in the brake master cylinder & repeat the process for the other 3 corners/wheels Once done your brake pedal should fell firm & Not spongy, If you get a spongy feeling when braking after this then there is still air in the brake lines & the system needs to be bled again, of course if you have done it right then your brakes should feel firm underfoot. Please don't forget to rate me, regards, Paul.

Spongy brakes


So long as the brake booster is working, test it by turning on the engine, press the brake pedal all the way down, then shut off engine keeping your foot on the brake pedal, if the pedal comes up slightly pushing against your foot then the booster IS working.

Did you BLEED the brakes??????
