You bleed it like you would a normal system but you must use the boost assist to do it, in order to do this start the truck pump the brakes three times and bleed that cylinder farthest away from the master cylinder do this twice or until you get clear fluid to run out. add fluid for every cylinder before moving on. Do this for each wheel and after doing all four wheels you should be ready to go. If it feels mushy you will have to bleed it a second time. But you must have the engine running to bleed the brakes unless you have a power bleeder. You may want to bleed the master cylinder first to do this add fluid to the cylinder then pump brakes three times crack the front line open and allow it to bleed air rout of the line do the same for the rear master cylinder once yo get solid fluid from the master cylinder you can dot the same for the ABS then do the wheel cylinders and wheel calipers. This needs to be done sometimes, be sure to never let the master cylinder run out of fluid and check it each time you bleed the wheel cylinders.

    I hope you were able to bleed them it's tough when you don't know for sure and some you just have to have a bleed pig iron to bleed them. The newer cars are changing it so you don't have such a pain in the rear to change the master cylinder. Just so you know the first one I ever did in the early 80's I had to buy a pig iron for $240.00 and it was a first time for me. (Grin) I had brake fluid everywhere before I had the back brakes bleed. What a mess. Lucky now The car manufactures listen to mechanics now. This helps speed up repair process and keeps the costumer happy and not waiting for days. Thank you for rating, that is something that we value as much or more than money. good luck.

This requires an electronic special tool to open the ABS pop valves, there is no other way to bleed the module, u will need to have the dealer finish the bleeding or a brake shop with the tool.

94chevy 1500 can't get the rear brakes bled


I had a experience with a car that REFUSED to let all air out its lines, and a friend of mine bought 4 vise grips, and gently grabbed the three hoses (from each wheel) that where not beeing bleed.
first he grabbed all four wheels, and notices a slight mush on the pedal and said that the master cyl was not properly bleed, he bleeded the cyl in a bench, then assembled the cyl and now the pedal was very stiff, then procedded to remove rear-right hose, and the pedal almost went to the floor, THERE WAS THE BUBBLE!, and bleeded acordingly, then reatached the vise grip on the OK line, and released the one on the rear-left, slight mush and bleeded, and so on. each time he tested for possibly air bubbles in each sector (master cyl, or lines, or caliper or aux cyl itself).
BUT!, IF your master cyl is NOT pumping fluid to the rear, probably the proportioning valve is broken (if yours has ABS, might the abs valves are dirty, and thus NOT closing and letting pressure go other way, because a failed abs pump SHOULD behave transparently, I mean , not interfering with the braking operation)
get quality FLARE WRENCHES, because the air bubble MIGHT not be right in the bleed bolt in the caliper/aux cyl.

Provided you have no leaks then you still have air in the system and need to bleed each wheel and the master cylinder. You may want to use a pressure bleeder to do this but you can do it the old fashion way with someone pumping up the brake and holding it when you open the wheel bleeders just make sure they do not allow the pedal to return before you get the bleeder shut.

No brake pressure...


I would keep bleeding. If there is not any brake fluid leaking, there must be air in the system. with the master cyl cap off, open one bleeder valve on the front and let it bleed for 10 mins. close and repeat with the rest. there must be an air bubble in the system! good luck

Brake master cylinder


Someyimes if the MC. level gets too low, air bubbles can get trapped in the hydraulic control unit for the ABS. and it won't matter how much you bleed the brakes, that bubble will b stuck and will cause spongy/no pedal. it this happens, only way to get it out is ABS service bleed with a professional scan tool (ones at oreilys won't cut it) to cycle the valves then re bleed system. most shops charge under $150 for this...worth a shot

Changed both front (rears are drums and did not change) brake calibers and pads on my 1998 F150 pickup 2 wheel drive. In doing so I let the master cylinder go empty. How do I bleed the brakes now. I have...


your probably going to have to bleed the entire system.1st try & bleed the master cyl.
basicly the same as you would bleed the front/rear brakes. pump pedal & hold while someone
loosen the brake line on the master cyl. after m/c is bleed move to r/r,l/r,r/f,l/f wheels in
that order. if you have abs brakes & you got air in the pump a scan tool may be needed
to bleed properly.

I have a 2001 gmc sonoma 4.3 replace brake lines on back i am not getting any fluid to rear wheels i tryed bleeding sys with help diconected abs sys to reset to defalt no abs light is on stumped


a special tool is required to hold the ABS hydraulic control unit popit valves open during bleeding of the brakes, without this special tool you will not be able to get the air out of the system, most good brake shops have this tool or of course the local Chevy dealer or GMC dealer. I am a dealer tech and know this information is correct..

the master cyl must be filled and bled before install.after installing new bled master cyl,bleed all calipers.once you are sure there is no air left in system then you will need a scan tool to perform a abs service bleed.if you do perform the abs service bleed with a scan tool the brake pedal will be soft and start to fade.
