If the shoes are adjusted to where the drum drags on the shoes while turning the drum,then the master cylinder is the most likely cause,some times the master will by-pass and cause this,and ,or will leak fluid out the rear of the master into the booster.

How do you bleed the brakes on a 2006 chevy silverado 1500

  • Fill the master cylinder with brake fluid before beginning. Jack the car up so that the two rear wheels are about six inches above the ground. Slide under the right rear wheel and look at the back of the brake system for a small bleed valve. A bleed valve is a hollow bolt. When loosened it will allow the brake fluid to flow out and result in the vehicle having no brakes Fit a rubber hose over the end of the bleed valve. Make sure it forms a tight seal and make sure the free end is below the level of fresh and clean brake fluid. As the brake fluid in the line pushes out of the system, you will see a bubble come from the end that is under fluid.Have a helper sit in the driver's seat and follow your instructions. Tell your helper to pump the brakes hard a few times. Open the bleeder valve and tell your helper to press the brake pedal firmly down to the floor and hold it there until you indicate otherwise. Close the bleeder valve and have your helper release the brake pedal. Repeat this process until you see a small bubble ejected from the tubing under the surface of the brake fluid in the jar. Once you have finished with this wheel, move to the left rear wheel. Before you begin the next wheel brake, refill the master cylinder reservoir. Get set up and repeat the same steps for this tire.The next two wheels you will bleed are the right front wheel and then the left front wheel. Bleed the wheels in the order of the longest brake line first and then working towards the shortest brake line. Refill the master cylinder reservoir before beginning each new wheel. Once the rear brakes are finished, lower the car and jack up the front of the car. Remember to road test the brakes and make sure they operate well

    Can not get good brake after bleeding.what the best way to bleed it

    the correct way to bleed brakes requires 2 people. you start from the wheel farthest from the master cylinder which would be the passenger rear, pump the brakes 5 times an hold it down on the 5th time open the bleeder screw an close it, then have your helper pump the brake pedal 5 times and hold it down on the 5th time open the bleeder screw then close it, repeat this until you have a solid stream of brake fluid coming out with no air pockets. then carry these steps over onto the driver side rear, passenger side front, and then finally the driver side front. make sure to fill your master cylinder with brake fluid in between each wheel, this is very important because if you dont you will get air pockets in your lines an have to do it all over again

    How do I bleed my brake lines on a 1999 Oldsmobile Bravada

    This job is a lot easier with two people but you can do it with 1 if you have to. Have someone sit inside and pump the brakes 3 or 4 times and on the 4th pump hold it to the floor(all the way to the floor and don't let up at all). While they hold it to the floor you take a little end wrench and (Starting on driver side front going to pass. front next then pass. back and so on) you should already have the tire off before pumping brakes. On the caliper(the thing that holds the pads) there is a little bleeder nut Should be near where your brake line goes into the caliper. Now while they hold the pedal down you loosen that nut just a little bit and it should spit a little bit then maybe some fluid will come out maybe not on the first time but it does happen. Just dont leave it open longer than a couple seconds. Just long enough for air to escape then tighten back down. Repeat all those steps about 4 or 5 times for each tire or until brake pedal feels hard to push in. Make sure while your bleeding that you check your master cylinder often if you let it run out u will have to start over from the beginning. Also make sure who ever is holding the pedal do not let up when bleeder valve is open. Same thing. I just wantedn to m

    Have an 89 festiva changed 5 master cylinders and still cant bleed front driver and rear pass wheel and also changed distribution block 3 times. i cant bleed it rite from the front port of the master...

    Section 06-06: Hydraulic Brake System 1992 Festiva Workshop Manual GENERAL SERVICE OPERATIONS Manual Bleeding
    1. Read Hydraulic System Bleeding General Information.
    1. Clean all dirt from the master cylinder filler cap.
    1. Fill the master cylinder with the specified brake fluid. During the bleeding operation do not allow the master cylinder to run dry.
    1. If the master cylinder is known or suspected to contain air it must be bled before the wheel cylinders or calipers. To bleed the master cylinder, loosen the front line fitting and have an assistant push the brake pedal slowly through its full travel. While the assistant holds the pedal, tighten the brake line fitting. After the line fitting is tightened, the assistant may release the brake pedal. Repeat this procedure on the rear brake line. Repeat the entire process several times to ensure all air has been removed from the master cylinder.
    1. Remove the bleeder screw cap from the appropriate rear wheel cylinder.
    1. Position a box end wrench on the bleeder fitting.
    1. Attach a rubber hose to the bleeder fitting. The hose has to fit snugly around the bleeder fitting.
    1. Submerge the free end of the hose in a container partially filled with brake fluid.
    1. Loosen the bleeder fitting approximately three quarters of a turn.
    1. Have an assistant push the brake pedal slowly through its full travel and hold it there.
    1. Close the bleeder fitting.
    1. Have the assistant release the brake pedal.
    1. Repeat Steps 9 through 12 until air bubbles cease to appear at the submerged end of the bleeder hose.
    1. When the fluid entering the bottle is completely free of bubbles, tighten the bleeder screw, remove the bleeder hose, and install the bleeder screw cap.
    1. Repeat Steps 5 through 14 at the appropriate diagonal front caliper.
    1. Check the master cylinder fluid level. If necessary fill it to the correct level with the specified brake fluid.
    1. Check pedal feel. If the pedal remains spongy, repeat the bleeding process or, if necessary, refer to Diagnosis and Testing in Section 06-00.

    Brake fluid is not coming out when i open the bleeder at the rear wheel on 89 ford tempo

    Good day Robert W73, there should be a metal pipe leading from the master cyclinder to the rear wheels and to the front wheels. Try loosening the pipe on the master cylinder and pump the brakes. It might be that there is an air lock in the master cylinder. By loosening this pipe the air forsing the brake fluid back will be released. As soon as the clean brake fluid comes out of the pipe tighten the pipe again and pump the brakes. Then step on the brake pedal and hold it in, while the brake pedal is depressed open the bleeding nipple and close it again. Repeat this procedure till you have clean brake fluid comming out of the bleeding nipple. Just remember to bleed all the wheels starting at the wheel furthest from the master cylinder and working your way to the closest wheel.

    I hope this helps. If it does not help you might need to replace the seals on the inside of the master cylinder or you will have to replace the master cylinder itself as there might be pit marks on the inside causing the hydraulic fluid to bypass the seals.

    How to bleed brakes on a 99 jeep wrangler?

    Hi, there are bleed screws on the cylinders located on the top and back of the brake plate right where the brake line is attached. Have an assistant pump up and hold the brake pedal, open the bleed screw on one side and the pedal should go to the floor, have the assistant continue to hold it down until you have tightened the bleeder, now repeat until no more air comes out. Repeat for the other side.

    Replaced frond brake pads, brakes now go all way to floor, tried to bleed but cannt get brake pedal at all. Some fluid coming out of bleeders during bleeding.

    you shouldnt have to bleed anything when just doing brakes,unless you opened the bleeders and this did not have to be done, if this is what was done then bleeding is needed,close all bleeders, have someone in car, pump pedal 3 times and hold down open bleeder tell them to keep preasure on pedal as it goes down then close bleeder and then tell them to pump again and hold do this a few times on each side starting at the right rear wheel then to left rear then right front then left front always keep an eye on fluid level in master cylinder always keep it full, dont let it empty, bleed all wheels,

    Having trouble bleeding brakes on my ford f150 4x4 i had to put a new caliper on left front.i bled the front brakes but still cant gmuch of a  there a switch or valve i need to turn off so...

    1 Siphon off the old brake fluid in the master cylinder reservoir under the hood.
    2 Fill the reservoir with new brake fluid (don't reuse old fluid as it holds moisture and will corrode your brake system).

    3 Start with the brake farthest from the Master cylinder, usually rear wheel, passenger side. Pull off the rubber cover on the bleeder valve. Attach the aquarium air line to the nipple on the bleeder.

    4 Have your assistant pump the brake pedal up and down 3-4 times, then hold the pedal down fairly hard.
    5 Open the bleeder, let fluid flow out through the air line into a waste container. (preferrably a clear bottle so you can see any air bubbles escaping the system). When the fluid stops and your assistant's foot hits the firewall (brake pedal all the way down), close the bleeder valve immediately!
    6 Go to step #4 above and drain more fluid out of the bleeder valve until clean fluid comes out. Check the master cylinder every time and top it up as necessary. This procedure uses lots of fluid.

    7 Now move to the rear brake on the driver's side. Go to step #4 and repeat the same procedures above until clean fluid comes out of the bleeder valve and no bubbles.
    8 Next is the front brake, passenger side, same procedure. Then the drivers side and the same procedure.
    9 When finished check for any leaks, remount rubber covers on the bleeder valve nipples. Remount all wheels, re-torque lug nuts after 50-100 miles of driving.
    10 Start vehicle and depress the brake pedal. It should feel much less spongy than before this procedure. If not, there is air in the system, start over. Bleed everything again.
    Note: if you assistant releases the brake pedal before you can close the bleeder valve then air will be introduced into the brake lines. This is no good! Before you start tell your assistant you will tell him/her PUMP, HOLD DOWN, RELEASE commands.

    That's it, you're done. Congratulate yourself on saving some cash instead of handing it over to a mechanic.
