SOURCE: replacing power brake booster

You don't need to remove the pedal to get the booster off,it just slides inside,so when the booster is unhooked it will just pull out.



Please rate this a fixya.

SOURCE: 2002 Chevy silverado 2500HD No power steering or brakes

The shaft in your power steering pump has broken. Your brakes work off of a system known as Hydra-Boost. If this shaft is broken then your steering and brakes are lost. I contacted GM after I had my power steering pump replaced and they sent me a check for the cost of my repairs. My truck was not under warranty or recalled but earlier models (2500HD) had been recalled for the power steering pump shaft. The pump was the same part number for my 2002 2500HD as the recalled years. Good Luck!

SOURCE: Power steering and brake line location2002 Chevy Silverado 2500HD

the power steering lines are very short hoses approximately 8 inches long that go from the power steering pump down to the steering box, which is located on the frame, just below the pump. The brake lines run from the master cylinder(where you fill it with fluid on the drivers side firewall) down to the frame, and then follow the frame both directions; both to the front end and the rear end, along the drivers side frame rail, just on the inside of it. The fuel line runs along the same path to the rear.

SOURCE: 2004 Silverado crew cab has rattle around steering

If you feel this rattle while driving at low speed or turning at low speed it is likely a worn out steering shaft coupler, it is very common.

How to fix brake booster " ?"


You will need to replace the booster. Unbolt the master cylinder from the front of the booster under the hood, then go inside of the cab and under the dash unhook the actuator rod from the brake pedal and remove the 4 nuts that hold the booster to the firewall. Then make sure to unplug the vacuum line from the booster under the hood and pull the master cylinder off of the booster being careful not to kink the brake lines. The booster should come right off.

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.

I need to top up the power stering fluid and need to know what tipe to use 1988 chevy silverado C3500 454 The power steering looks like it is incorperated into the brake booster


power steering is at the front of the engine and runs on the belt. The reservoir cap looks like this:
73b4b95.jpg To top off steering fluid, use standard steering fluid.

The reservoir in front of the brake booster is the brake master cylinder reservoir. To refill, use standard brake fluid. If it the truck is using brake fluid, check for leaks at the back of the master cylinder and at all wheels.

Please let us know if you have more questions.

ABS and BRAKE light at the same time


push the pedal and see if it goes to the floor slowly or fast, if so,some thing like this i would lay on the ground in the back and have some one push the pedlal and hold it, look for fluid, like wet spot near the wheels first ( i have seen wheel cylinder go bad but not leak alot at one time so keep that in mind too) and make your way to the front on the driver side inside of the fram.i dont think its the master cylinder but see if you can see a wet spot at the bottom of the master and the booster( i seen masters not leak as will )

leaks will make the ABS lite come on

Engine pulsates during idle and from second to third gear


Try checking for vaccum leaks, use carb cleaner and spray it around the base of carb, vaccum hoses, edges of intake manifold, take pliers and squeeze the big line to brake power booster & see if it changes, pull the pcv valve out and cover with your finger see if it changes idle.
