If you look down under the radiator in the area of the power steering pump, nestled in the crossmember you should see some brake lines going in and out of a rectangular steel block. It should also have a single wire going in the top. That is the proportioning valve which adjusts brake pressure to the wheels. One of these lines is likely the source of your leak. Hope this helps.

Soft brake pedal on 94 gmc sierra


in late model GM and Ford cars with quick take-up master cylinders, the quick take-up valve takes about 15 seconds to reseat after the brake pedal has been depressed, so you should wait at least 20 seconds before you press the pedal while bleeding. If the pedal is pumped too quickly while manually bleeding the system, you may never get the pedal to firm up. On a side note, did you check the level in the master cylinder after every 2 or 3 bleedin procedures? you could have been pumping air right back in the lines if the reservoir runs dry during the bleeding process.

Okay, Sounds like you have a bad brake bleeder on the right side. Check beforehand by calling the auto parts stores to see if they carry brake bleeders. It is absolutely necessary for all lines to bleed.
There is a pattern to use when bleeding brakes. The longest rear line first, next longest rear line, then the passengers front and finally the Drivers front.
As each line is bled. the Master cylinder should be monitored for low fluid. When the rear brakes are working, you will hear the brake springs work when the brake pedal is pressed.
It is possibly to have a plugged brake line which can only be determined once the brake bleeder releases the fluid. There can be variations in the brake adjustment, so before putting on the wheel, adjust the star wheel evenly from side to side. Hang (Fit) the drum to the axle and snug up with the lug nuts. Spin the rear wheels and note that each side is evenly touching the brake linings.

Replaced some brake line, rear pads and one rear wheel cylinder. Now no pressure and nothing happening when trying to bleed.


Does the car have ABS ? And does it have an equalizer block for the 4 wheels ?
It sounds like the ABS has been affected, or there is an equalizer block that is stuck on the front wheels only.
Can you open the bleeder or the rear line on the master cyl and get fluid to come out by depressing the pedal ?

Sounds like you may have a hydraulic leak somewhere. Check the rear wheel cylinders and front brake hoses going to the calipers.

Brakes squishy no leak


Mushy / squishy brakes are usually caused by the brake master cylinder seals failing. You can buy a rebuild kit or a re-built replacement master cylinder. I would recommend the rebuilt master cylinder as all the detail work has already been accomplished and it is not a huge expense. The key is to make sure that your use a bleeder kit to "Pre-bleed" the master kit before installation. Your making sure that the master cylinder is free of air before installation. If you instal it with air in the system it wil take you the better part of a quart of brake fluid to bleed the whole brake system via the wheel cylinders. What will happen is after you install the master cylinder the brakes would still be mushy and until you got the residual air out of all of the lines it would appear and act just like it did before you changed the master cylinder.

Thanks for using FixYa,
