You can also vacuum the fluid through the system to the back with a vacuum bleeder attached to a rear bleeder.

Cut that out. Replace it with a compression fitting. Bleed the system.

Does sound like you need a new master cylinder. On a 2000 you wont need to back bleed. You will just need to follow the instruction and bleed the master and all four points. you will probably need to bleed the ABS block and proportioning valve but only if they have bleeders on them.

SOURCE: cant bleed out brakes

It takes time, do you know the sequence to bleed the brakes? Most cars r different. And you have to keep pouring brake fluid, That is a two person job. Make sure all lines r connected to MC and not leaking. After a while if nothing comes out MC could be diffective.

you may have a ABS problem. I would drive it and attemp to skid the tires an dsee if the pump activates. sometimes this will unstick any valves inside the ABS unit. you may need to have a qualified repair shop check deeper. the ABS will have a code, and a scanner will be needed to check further.

I have a 1997 chevy blazer that has a brake fluid leak just underneath passenger rear seat on drivers side and cannot find how to see what the heck is leaking what is the best procedure to figure out what...


you most likely have a brake line rusted threw, cut the line ahead of the leak and after the leak and splice in a new piece of brake line, it will have to be steel, you can not use rubber. if you take the line to a parts store they can size it up and get you a piece of steel line and some pressure fittings to put it back together, after you repair the line then you will need to bleed the rear brakes.

Brake pedal to floor have replaced brake pads and master cylinder


Did the pedal go to the floor beforehand? Was the master cylinder leaking, and did you bleed it properly? If the master cylinder was not leaking, check your brake lines going to the rear wheels.

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.

I have a 2000 chevy blazer. had to short fix left rear brake line with hose and clamps. bled air from that side, brakes were soft in the pedal. checked right rear for any air had none. brakes still feel...


do not drive the vehicle. remove the hoze. replace it with steel line. rubber hoses are not meant for the high pressures of brake lines. it is expanding when you press the brake pedal. very unsafe.

I re placed the master cylender and now i got no brakes in the back at all


You will need to bleed the system. If you did not bleed the master when you installed it, if it has bleed valves, use them to get the air out...if not, step down lightly on the brake and at the same time, loosen the line fitting a bit till fluid comes out. Then, bleed rear brakes the same way using bleed screws on the cylinders or calipers. Begin at right rear, then left rear, then r/f and l/f. Don't permit the master to run dry or you will have to begin all over again. Also check all lines to make sure nothing under the vehicle is leaking. While bleeding don't take your foot off the brake till the bleeder you are working on is closed, and don't push really hard on brake as that can damage the cylinder internals.

1997 Pontiac Grand Am Front right brake caliper not working right


Check the brake hoses. The rubber hoses that come from the hard line, (Metal), to the caliper.
If these are the original ones that came with the vehicle, they are overdue to be changed out.

Do they have any weather cracking on the outside? No? That's okay as they break down on the inside, and sometimes this isn't apparent from the outside.

The rubber brake line is a composite. A sheath on the inside, then a steel braided hose, then another sheath on the outside.
The sheath on the inside breaks down, and a piece of the rubber compound blocks the hose opening, when you step on the brake pedal.

The brake line can also swell up a little, as you step on the brakes, causing that spongy feel.

The master cylinder brake lines broke before the proportion valve


Obviously you have a bunch of badly rusted lines. Better they failed while you were working on them rather than driving down the road! Carefully inspect the remainder of the lines and if in similar condition to the ones that failed, you need to replace them. When finished and system is tight, then bleed out system. (check it twice to ensure all air is gone.)

Pull to the left, Brakes


Sounds like it was pulling before the brake job...if so the only thing you didn't replace was the rotors, I assume you turned them? and did you see hard spots on the rotor? discolored area that didn't cut the same......switch the rotors left to right and see if the problem moves or just replace them if they've been cut twice.
