Have the engine running & bleed the brakes again

Have someone in the vehicle slowly push the brake
pedal,never pump.

When you are driving, do you pump your brakes,NO

Pushing the brake pedal only moves the piston in the
brake cylinder about 1",that is all
That amount of movement will build up to 2,000 lbs
of pressure. So no pumping,does nothing

As the person is pushing the pedal down,someone
else opens & then closes the bleeder valves while the
pedal is still going down.

Then you wait on the person in the car to start over.
Real simple.

Assuming you paid for all that work,why do you have
issues that you didn't have before.

Don't want to discuss what the pros do,but we have
a thousand people on this site every day with problems
that they shouldn't have and are lighter in the wallet

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.

Brake pedal goes all the way to the floor, will slow the car a little, but wont fully brake. master cylinder is fine, calipers and pads are new, brake lines look okay, it's holding brake fluid fine, lines...


must be something you have overlooked. clamp off the front brake hoses and rear hose. if you dont have the propper clamps use g clamps or locking pliars. try the pedal then. if it still goes to the floor its either air in the lines or the master cylinder is no good..Bleed the master cylinder at the lines first,then work back.

try disconnecting the front line, have someone else then step on the brake pedal and hold it down while you re-install the line. If that doesn't do it, you probably did get a defective master cylinder.

After replacing drive side caliper, both front disk brakes, and rear drum brakes, bleed all three lines, both my front calipers lock grinding my front brakes. I am going to re-bleed my lines tomorrow but...


I assume you mean that you replaced the front pads and rear shoes. Or did you also replace the disks and drums?? Either way you should be ok unless you also replaced the slave cylinders on the rears.
The fluid flows back up to the Master Cylinder as you squeeze the calipers and the slaves to fit the new parts in. Some people pre-fill the caliper to reduce the amount of air and make bleeding easier.Now .....Grinding better be a wrong choice of words. Possibly you spilled fluid on the pads while bleeding the lines. This will cause a binding and shuddering when you apply brake pressure. This will also make you think the lines are not bled properly because of the increased pedal pressure you are putting on the wet/lubricated front pads. If so, replace the pads. Don't try washing them with aerosol cleaner cause it takes more time and money than simply changing them.

I have a slow brake fluid loss. I think it may from the master cylinder. Are there any seals in the lines that go into the master cylinder unit.


no they are inverted flare fittings no seals check all lines and calipers/wheel cylinders if all are dry remove the vacuum hose from the booster if there is brake fluid in the hose the master cylinder is bad

Changing 4 calipers and there is no oil com out when try to bleed


The master cylinder supplies the pressure to the brake fluid that travels between the maste brake cylinder resevoir and the brake caliper pistons (through the brake lines. If the master cylinder fails there will be insufficient compression of the brake fluid to make the calipers operate as designed. Leaks in the brake lines and/or cylinders is a possibility, and unrelated to functionality of the master cylinder. Also, pistons located in the brake calipers can form a corrosion ring on their inside walls if there is breakdown in the brake fluid or moisture that gets into the lines. Operating the vehicle when there is insufficient brake fluid in the master cylinder resevoir can also lead to air getting into the brake lines, causing bad working brakes. Air compresses more than brake fluid, and the master cylinder isn't designed to compress air in the brake lines. Sounds like a bad case of "lack of maintenance", as opposed to bad advice from the mechanics. That said, there's no excuse for bad installation. But, it's tough to improperly install a brake line since they are nothing more than hollow metal tubes. There should be no rubber connectors installed in the brake lines. When bleeding the brake lines one must remove all of the trapped air before you will see any fluid appear. If the valves in the master cylinder are not properly operating the master cylinder will not allow the brake fluid to get into the brake lines.

Hope this helps.

Just replaced master cylinder on 1990 aerostar and bled the brakes, still the pedal goes to floor and i have no brakes


Did you bench bleed the master cyl. before installing it? then when you installed the new master, did you bleed all 4 points? If yes, then check all for points for leaking caliper/s and leaking wheel cylinder/s. If the van has ABS, check the valve body for a bleeder screw and see if air bleeds out of it. If you've checked everything twice and did everything right then your new master cyl. may be defective.

Unable to bleed front brakes


loosen the front brake line that goes to the master cylinder fill master cylinder up with fluid and bleed it first by attaching a flexible line from master cylinder front brake side submerge that line into jar of brakefluid keeping air from entering line get someone to pump brake pedal while ur holding line in a jar keep refilling the brake resivoir so no air gets in, once the master is bled front brake side then reattach the origional brake line then remove bleed screw from caliper and let fluid gravity flow down to calliper then bleed the normal way. more than likely your master cylinder has air trapped in the front portion good luck
