Brakes had to change the left rear caliber. tried to bleed the brakes and lost all braking. Then I changed the master cylinder and got some braking back, but pedal goes all the way to the floor. Again tried to bleed and again lost all brakes. changed the master cylinder again (froze) and have brakes, but still the pedal goes all the way down to the floor. Any idea how to fix this?

    I sat in the car and pressed the brake when my friend told me to. He was back at the caliber.

    Go to the auto parts store and get a brake bleeder kit,You can use them for free at auto part stores that have the lend a tool program,Like advance or autozone,But they are cheap so if you can't borrow one ,just go ahead ad buy it,It will save a ton of time.

fill master cylinder, start at right rear. the way I do it is make sure cap is back on master cylinder. pump the brakes a few times then hold them. have another person open the bleeder valve at the tires until brakes go to floor. hold them down until bleeder is retightened but be sure master cylinder is not out of fluid. then go to left rear and do the same procedure, then right front, then left front. check fluid and if air is all out there should be brakes. good-day ! THIS IS HOW I HAVE ALWAYS DONE IT ! heres a little trick of sorts. you can change a master cylinder, and if you bench bleed it first. and no fluid is lost from the master cylinder lines you do not need to bleed the whole system. but make sure cylinder is full of fluid before putting on vehicle and all air is out of master cylinder.

your probably going to have to bleed the entire system.1st try & bleed the master cyl.
basicly the same as you would bleed the front/rear brakes. pump pedal & hold while someone
loosen the brake line on the master cyl. after m/c is bleed move to r/r,l/r,r/f,l/f wheels in
that order. if you have abs brakes & you got air in the pump a scan tool may be needed
to bleed properly.

to bleed the brakes & should be done w/proportioning valve in place - you start at farthest corner - right rear, left rear, right front and left front.... If you suspect proportioning valve you can pick them up cheap at any salvage yard.

My brakes will not get hard. The pedal goes to the floor. I just changed rear caliper and rotor on the drivers side.


DId you bleed the system after you changed the caliper? If the Master cylinder lost it's fluid while you were changing the caliper, then there is air in the system and you need to bleed the entire system. start with the REAR RIGHT, then the REAR LEFT and then the FRONT RIGHT and last the FRONT LEFT. make sure the master cylinder NEVER runs low on fluid and DO NOT re-use any fluid that you get out of the calipers.

All 4 corners of the car need to be bled after replacing the master cylinder. Start with the right rear, than the left rear, than the right front, and finish with the left front. Keep bleeding each one until absolutely no air comes out. Make sure you do not let the master cylinder run dry!

Changed brake pads! Success.. Now I need to bleed the brakes.


To bleed you brake system, you will need brake fluid, a jar, and a couple feet of small hose that fits tightly on the bleeder screws. You should not need to remove the tires to access the bleeder screws, but you may need to raise the vehicle a bit to access them.

To bleed the system, start with the right rear wheel. Put a couple inches of brake fluid in the jar, attach the hose to the bleeder screw, put the hose in the jar of brake fluid, then open the bleeder screw. Once the bleeder screw is open, pump the brake several times. Next, close the bleeder screw. After you close the bleeder screw, remove the hose and jar, then fill the master cylinder with brake fluid.
Repeat the steps going to the left rear second, right front third, and left front last.

Once you have bled the system your brakes should be tight and working nice.

I hope this information helps you, and I wish you luck on your repair.
