Bleed brakes bleeder

I do believe you have to put your truck on a scanner to bleed the brakes properly. I have done it a few times to get the pedal back up. After some one else has worked on them. Usually it's because the ABS pump was run dry. But check for fluid around the brake booster, it will be wet and eating the paint off it. Replace the master cylinder first. Bleed, and if you still have the problem. Get it on a scanner.

All four brakes lock up on my 2003 siverado 2500hd

check then pedal free play . That is the distance the pedal travels before the brake rod hits the piston in the master cylinder. If there is no play then there is a blockage in the compensating ports that is allowing a build up of pressure in the lines.

2002 chevy silverado 2500 hd with duramax no brake or steering power. do I need to replace or repair hydro booster?

It definitely sounds like the hydro booster. There are videos on YouTube that shows you how to do either. Depending on your skill level will determine which one you do. The main issue is bleeding the air out of the booster. It can be difficult. You will also need to bleed your brakes completely afterward. GMs are notorious for having the hydro boosters die on them.

Rear brakes dragging on one side 2003 gmc 2500hd 4x4 seems to be after brakes were crowded harder than normal

tim, I'm not sure if you have rear disc or drum brakes, but this is usually a caliper or brake cylinder (at the wheel) problem. If you have drum brakes, check for any problems like broken springs on the shoes, which would result in parts floating around, and brakes not releasing properly. The same for disc brakes, make sure nothing has become loose (mounting pins for caliper). If you find it is a brake cyl/caliper problem, you will need to rebuild or replace it. Make sure you bleed the brakes for the entire system (you want to flush out the system to prevent further problems), as old brake fluid can become contaminated (brake fluid absorbs water, which corrodes calipers and brake cylinders, leading to failure of those components). Last, make sure it isn't a parking brake that is not releasing. Parking brake cables corrode from exposure to the elements and can bind up, causing the brakes to drag. Use something like WD-40 on the cables to keep them operating correctly.

Mushy powerless brakes . changed pads,rotors,powersteering pump.

Mushy brakes are almost always 1 of 2 things:
  1. Air in the brake line; when brakes where changed they weren't bled; this would cause a soft brake pedal.
  2. Most common reason for a soft pedal is a bad master cylinder. Once they become faulty they fail to provide the pressure required to adequately stop the vehicle.
Either way, have this checked out at a brake shop immediately. A soft brake pedal is not something to be fooled with.

Cant get brakes to bleed properly

Here's all the tricks for bleeding brakes that I've got:
1. keep the master cylinder FULL.. check it often. if you **** air into the lines, you're going to need to start all over... so keep it full.
2. Have a assistant pump the brake pedal and hold pressure- when you open the bleeder screws at the wheels, the pedal will drop. Make sure the assistant doesn't let off the pedal until you get that bleeder shut again. Then he can repressurize again (keep an eye on your fluid level).
3. Start at the farthest wheel. then work to the closest to the master cylinder.
4. Then refill the fluid as needed.
5. You may need to "center" the brake lite (dash indicator) you can do this by having the assistant hold pressure while you bleed the line at the master cylinder (quick and abrupt) you may have to do the front or the rear line (on the master cylinder).
Good luck...hope this aolves your issue..
