2002 chevy silverado 4x4, brakes

remove the drive shaft then remove the brake hoses and e brake cables remove the breather hose then remove the bolts at the springs or links which ever it has

Do you have someone slowly pressing on brake
pedal,as you open the bleeder valve & close before
the pedal reaches the floor & repeat 8 times or so

You never pump brakes when driving or bleeding

Do not let the master run dry or you start over

I never had that issue in 48 years & I have no special
abilities

you have to bleed them all, starting at the passenger side rear,, then the drivers rear, up to the passenger front, and finally the drivers side front. and it takes forever unless you have a bleeding tool, autozone and a couple of other parts stores have a reversal tool that you can borrow or rent,, it comes with a pump and you have to buy brake fluid for it,, you attach it to the bleeder valve on each brake, and instead of using the master cylinder to force air out at the brake itself, it goes the other way,, it fills the lines from the brake to the master cylinder, forcing the air to the master instead,, but I would try doing them in the order I stated first ,

Try opening a front bleeder and depress the pedal ALL the way,should feel a light "tic" as it reaches the bottom,close the bleeder and try to bleed the rear again,but instead of pumping ,just take the master cover off ,open the rear bleeders and wait 10 min or so for the fluid to gravity bleed out the air. Thinking the proportioning valve is tripped so no fluid is allowed to reach the rear,opening the front should reset the valve . If there is alot of air the valve will just trip again if you pump the pedal,hence the gravity bleed.

On disk brakes, the bleeder is near the top of the caliper pointing toward the inside.

On drum brakes, the bleeder is above the axle bearing just above where the brake line attaches. If you have more questions or need instructions please let us know.

u may have to pull the bleeder of and clean it out with a small drill bit it could be blocked with rust or dirt.

You will need to purchase two of them,and put them together with a coupler.

Hello,
I hope this helps.







Thank You,

It sounds like the rear calipers are bad. Raise the rear wheels and see if you can turn the tires. If you can't, open the bleeder. If you still can't replace the caliper. If you can turn the wheel after you open the bleeder, replace the brake hose to that wheel.

have one person in the blazer pumping the brake pedal and then hold to the floor, crack the bleeder then tighten, release pedal, repeat till all air is out one side at a time, if this does not work then your ABS unit is bad witch if u follow your lines from your master cylinder u will find a black box with a motor on it, or the master cylinder itself is bad, it also can cause u to have no pedal, replace the master cylinder first, most likely cheaper.
