SOURCE: i have a gmc 2500 4x4 and rear brakes locking up

Do you have a/the proportioning valve in your system? Pin needs to be pulled out for centering while bleeding.

SOURCE: 1996 T-100 dash brake light will not go out

The brake fluid level sensor in the master cylinder is stuck in the lower position which completes the circuit to illuminate the light.. Try tapping lightly on the side of the reservoir to loosen it. If that does not help, you will need to replace the level sensor.
Thanks for choosing FixYa for assistance.

ANTI-LOCK BRAKE SYSTEM (and HCU-Hydraulic Control Unit)
General Information The 4-Wheel Anti-lock Brake System (ABS) is an electronically operated, all wheel brake control system. Major components include the power brake booster, master cylinder, the wheel speed sensors, and the Hydraulic Control Unit (HCU) which contains the control module, a relay, and the pressure control valves. The system is designed to ****** wheel lockup during periods of high wheel slip when braking. Retarding wheel lockup is accomplished by modulating fluid pressure to the wheel brake units. When the control module detects a variation in voltage across the wheel speed sensors, the ABS is activated. The control module opens and closes various valves located inside the HCU. These valves, called dump and isolation valves, modulate the hydraulic pressure to the wheels by applying and venting the pressure to the brake fluid circuits. Some models are equipped with a Traction Assist (TA) system. The TA system senses wheel spin upon acceleration, turns on the Hydraulic Control Unit (HCU) pump and applies fluid pressure to the appropriate rear wheel. Two additional isolation valves in the HCU will also close to permit fluid to flow only to the rear wheels. The TA system monitors TA usage to avoid overheating the rear brakes. If the system does sense brake overheating, the ABS module will inhibit TA operation until the rear brakes are permitted to cool down.

SYSTEM COMPONENTS The anti-lock brake system consists of the following components:

  • Vacuum booster and master cylinder assembly
  • Hydraulic Control Unit (HCU)
  • ABS module
  • Wheel sensors
  • Pedal travel switch

On 1992-1994 and 1995-00 a scanner is used to perform the brake bleed. But on yours, I think it's different according to the manual.

What do you mean change the cal. on the rear also? Do you mean Caliper?

Testimonial: "Yes, I mean Caliper. Will the rear Calipers work with the lower pressure master cylinder? Thanks"

Kia K2700 front brakes binding, new master and load censor.


check the adjustment of the pedal for the master cylinder
the rod attached to the pedal must be free about 1" movement before the master cylinder is activated
if the pistons in the master cylinder are not free of the compensating ports tyen hot brake fluid will push on the calliper pistons and apply the brakes
the load sensor is only a proportioning valve to allow more pressure to the rear brakes under a loaded situation
you may have to take it to an accredited brake specialist shop to properly diagnose the problem

What would cause the Brake Calipers to stick and get my Rotors hot on my 1999 GMC JIMMY


The master cylinder. What you have is something that is pressurizing the front brake circuit but not the rear. The only possibilities would be the Master Cylinder or a proportioning valve.

Why even with new brake parts in the front and rear on my 2995 Ford f150 2wd truck would front brakes work but not back ? I even put truck on bay lift and hit the brakes and rear just kept spinning.


Bill:

Check your master cylinder. It could be a piece of junk lodged in the fluid port for the rear brake lines, or in the brake line its self. The fact that both rear wheels spin tells me that if it is a clogged line, it is between the two manifolds, (one next to the master cylinder, and the other where the rear brake line splits into two... one for each rear hub. Or it could be that the piston in the master cylinder needs to be replaced. I would disconnect one brake line at one rear wheel and disconnect the rear brake line at the manifold (near the master cylinder)and blow that line out with air pressure. . do not leave the rear brake line connected to the master cylinder as you blow air through the lines as you may damage the master cylinder piston packings. You'll have to bleed the brakes when you are done.

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.

Replaced all brake lines, rear wheel cylinders, front calipers. No fluid to rear brakes, no fluid to master cylinder bleeder. Fluid is in front brakes. How to resolve? Thank you


It sounds as though where the rear brake lines meet up with the master cylinder; there is probably a piece of dirt in the lines that could be blocking any fluid from getting in. To test this, I would remove the brake lines from the master cylinder and then remove the master cylinder. Once done, have the master cylinder cleaned inside out. This will remove the dirt particles that are clogging your lines.

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.

Hello. i have a 1991 audi 100. brake padel has become mushy but there are no signs of brake fluid leak on the master cylinder or the lines. the brake pads are new. thanks


Just because there isn't an external leak in the brake system doesn't mean there isn't an internal leak in the master cylinder. A mushy pedal is usually an internal leak in the master cylinder or leaking wheel cylinders in the rear brake drums. Check the rear brake wheel cylinders for fluid leaks, if there are none or you do not have rear drum brakes, your best bet is the master cylinder :)
