What kind of brakes do I need for my breifly?
BROUGHT VEHICLE INTO SHOP AND CHECKED OVER, PEDAL IS SOFT, IF YOU PUMP IT SEVERAL TIMES, IT HOLDS BREIFLY AND THEN FADES AWAY, THE REAR BRAKES WERE JUNK, THERE WERE CHUNKS OUT OF THE ROTORS, REPLACED REAR BRAKES, THERE ARE NO LINES LEAKING ON VEHICLE, REPLACED THE MASTER CYLINDER WITH A NAPA MASTER CYLINDER.
Why are my brakes so soft after replacing everything?
New front lines, pads, rotors, rear shoes, rear cylinders, drums, springs, adjusters, and levers have all been changed. After changing all this I had a very soft pedal. I bled the brakes three or four times with no affect. So I took it to the local mechanic. He said the master was bad.
Is there a brake pedal that goes to the floor?
I Have Changed All Brake Parts, Brake pedal goes to the floor? I have changed all brake parts, new calipers, new wheel cylinders, new pads, new master cylinder and booster and the cylinder rod adjusted.
What causes a brake master cylinder to fail?
For instance, the front right side and the rear left side would be worn down more than the front left and rear right. A failure of one of the piston seals in the master cylinder or a brake line leak could cause one circuit to fail.
How much does it cost to replace a brake master cylinder?
Instead, it will slowly sink to the floor. This could become a real driving hazard, so you’ll want to fix the brake master cylinder right away at this point. If you have a brake master cylinder that goes bad, the average cost to replace the cylinder will be between $320 and $500. The cost of the part itself will only be around $100 to $210.

Why is my brake system not working properly?
An undersized or worn out master cylinder: The master cylinder is the source of pressure for the brake system. When your master cylinder is too small, it’s not creating enough pressure and this results in your brakes engaging slowly and without enough force.
What causes a brake caliper piston to leak?
The brake caliper piston seal is leaking when you release the brake pedal. When you apply the brakes, the hydraulic pressure forces the seal to expand and prevents any fluid leak.
Can a four piston caliper be used with drum brakes on the front?
When any four piston caliper is used with drum brakes on the rear, a pressure reducing valve must be installed for front pressure control. Because of the small front tire contact area compared to the rear large slick contact area, the rear brakes must absorb more of the stopping energy than the front (contrary to a normal street car).
Is there air in left front brake line?
Still finding air in the left front caliper. So this past Monday, took it to another shop that specializes in brakes. This guy bled the brakes, replaced the other wheel cylinder (which was not working), machined the rear drums, cleaned and lubricated adjusters, clean and lubed caliper housings replaced the pins.
What happens when you press the brake on a master cylinder?
When the brake pedal is depressed, force is applied through the push-rod to the master cylinder piston. The piston actually has two seals, and push in two chambers of the master cylinder, with a line to each circuit. As the small master cylinder pistons are forced forward, brake fluid moves and hydraulic pressure builds.
Can a caliper not release cause brake drag?
Just like with the master cylinder not releasing causing the brake drag, a caliper not releasing and staying applied can do the same thing. If only one position is dragging, this could be the case.
What kind of caliper to use on master cylinder?
On our setup we are using the larger piston GM midsize calipers in the front and the smaller piston GM metric calipers in the rear.
The brake caliper piston seal is leaking when you release the brake pedal. When you apply the brakes, the hydraulic pressure forces the seal to expand and prevents any fluid leak.
