New brake line problem

I just installed a new brake line that runs from the master cylinder to a fitting in the rear drivers side and shuld be filling the hoses and the other brake line that runs across the rear differensial... but the front calipers are bleeding fine but as much as we pump the resivor stays full and no fluid will run through the new line i put on... thers no kinks and there are 2 fittings that make the line run all the way because i used 2 5 foot lines and a 3ft one that i cut with a line cutter and then put the fitting that attaches 2 the master cylinder over the 3/16th line then flared it perfectly... so can u PLEASE gimme something 2 fix it or try 2 fix it... is there some kind of sequence i should be bleeding them i???

I don't agree with the previous answer. I have bled many brakes on vehicles with ABS in the conventional way and so far have had no trouble.

The sequence remains the same as it always has but is usually less important today as it was before dual circuit braking - start at the closest bleeder to the master cylinder and work to the farthest.

It isn't a good idea to allow the reservoir to fully drain when changing a brake line and doing so often causes problems. In case of problems it is good to first ensure there is fluid delivery from the master cylinder by removing the troublesome brake line and use a finger to create a suction when the brake pedal is on the upstroke. if there is a good delivery there and the new pipe is clear it should now bleed normally. If it doesn't then repeat the process at the other end of the new pipe - and so on...

Any vehicle with ABS has to be bled by forcing fluid in at the brake nipple and through the lines UP to the master cylinder. You are trying to do it master cylinder to caliper.

SOURCE: brakes on 93 lincoln towncar seize up after driving 20 minutes.Had new front calipers,new brake line hoses and new

Do you know which one is holding on? I would if it has flexible hoses crimp off the rears with proper brake line crimps & drive but carfully as your brake function will be reduced. If it dosn't happen you know the problem lies in the rear if not you know its in the front. If in front uncrimp the rears & crimp 1 front drive & see what happens but with only 1 crimped the car will want to pull sideways under brakes if problem remains you know it is the other side, repeat with other side to make sure. This should let you know where the fault is if the fault remains its probably not any of the callipers or drums.

Replace mastercylinder'


The master cylinder in your Dodge Caravan is responsible for forcing fluid pressure to the four wheels when you apply the brakes. The master cylinder is also the main storage vessel for brake fluid. If the seals inside your master cylinder develop leaks, you will lose brake pressure internally. This could cause problems for the brake booster, as well as causing the brake pedal to sink to the floor when you press the pedal. The master cylinder can be replaced in about 30 minutes.
  • 1 Press the brake pedal a few times until you have a firm pedal.
  • 2 Open the hood and prop it up with the hood support rod. Locate the master cylinder, which is mounted to the brake booster on the bulkhead between the engine and passenger compartments, just in front of the driver. Spray the top area of the master cylinder liberally with brake cleaner. Push down lightly on the master cylinder filler tube and turn it counterclockwise to remove it.
  • 3 Locate the fluid-level sensor connector(s). There may be one or two sensors on your vehicle and they appear as wires, in a plastic housing, plugged into the side of the master cylinder. Remove each connector by depressing the locking clip and pulling straight out from the master cylinder.
  • 4 Remove the brake lines from the master cylinder by turning the fittings counterclockwise with the flare nut wrench. Gently pull the brake lines away from the master cylinder.
  • 5 Remove the bolts securing the master cylinder to the brake booster by turning the nuts counterclockwise with a socket and ratchet. Pull the master cylinder straight out, being careful to avoid spilling brake fluid on your vehicle's painted surfaces.
  • 6 Verify that the rubber O-ring seal is in place on the new master cylinder and then slide the master cylinder in place over the mounting studs. Thread the nuts onto the studs by turning them clockwise. Tighten the nuts to 18 foot-pounds. You may have to hold the booster actuator rod in position as you install the master cylinder.
  • 7 Fill the master cylinder with new brake fluid and thread the bleeder fittings into the brake line ports by turning them clockwise by hand. Install the rubber tubes onto the fittings and secure the tube ends in the master cylinder filler opening. Make sure the ends of the tubes are completely submerged.
  • 8 Depress the brake pedal a number of times, slowly and evenly, while a helper watches to ensure that no more air escapes from the bleeder tubes. Remove the bleeder fittings by turning them counterclockwise and carefully set them aside. Reconnect the electrical fittings by firmly pushing straight in until they click.
  • 9 Thread the brake lines into the proper ports by turning them clockwise by hand. Tighten the fittings to approximately 13 foot-pounds with the flare nut wrench. Have your helper press the brake pedal slowly and evenly five times and then hold it. Slowly crack open the front fitting by turning it a quarter-turn with the flare nut wrench and allow the brake pedal to fall to the floor. Have your helper hold the pedal on the floor as you tighten the fitting. Repeat this process until no more air bubbles appear. Repeat this process on the rear port.
    Retighten the fittings to 13 foot-pounds. Install the filler tube by placing it on the filler opening and turning it clockwise. Refill the master cylinder to the "Fill" mark or 1/4-inch from the top

How to replace a master brake cylinder on a 1989 oldsmobile 88 delta


First thing you need to do is bench bleed the new master cylinder.new master should have come with 2 plastic tubes and fittings.screw fittings into new master,fix tubes to fittings other end in to top of master where fluid goes.fill with fluid make sure the tubes are submergered in brake fluid for entire process.take a screwdriver and press plunger in rear of master.use short slow strokes to start you will see air bubbles in resovoir.slowly increase length of stoke watchin resovoir till no mome bubbles.now ready to install.Remove failed master,(loosen lines befofe removing mounting bolts)remove lines last.reinstall new master then remove bleeding tubes last install and tighten lines.Fill fluid replace lid,have a helper sit in car,loosen lines about half a turn.Have helper depress brake pedal slowly and hold down pedal untill lines tightened.when tight release pedal and repeat 5/6 times.fluid should come out of lines without any air when bled propperly.if failed master did not run out of fluid uyou should be finished.if pedal still soft/mushy will have to bleed a wheels also.use same proceedure but openening bleed screws not lines.may take many times to get rid of all air,you can see and hear the air exiting bleeders.keep an eye on fluid level while bleeding if u run out you are starting again

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.

When I start the truck, brake pedal goes down on it's own and will not come back up unless you pull it up , Booster?


The booster is working properly if the pedal goes down a little when starting the truck. Seems more like it's a master cylinder problem if it won't pump up.

REMOVAL & INSTALLATION Fig. 1: Disconnect the warning indicator at the master cylinder 88289p00.jpg
Fig. 2: Remove the fluid to minimize the amount that would otherwise inevitably be spilled 88289p01.jpg
Fig. 3: Unscrew the line fittings at the master cylinder 88289p02.jpg
Fig. 4: Hold a rag under the fittings to keep fluid from dripping all over things 88289p03.jpg
Fig. 5: Unbolt the master cylinder from the brake booster 88289p04.jpg
Fig. 6: Remove the master cylinder from the vehicle and set it in a clean location 88289p05.jpg
  1. Disconnect the negative battery cable.
  2. Apply the brake pedal several times to exhaust all the vacuum in the system.
  3. Detach and cap the brake lines from the master cylinder.
  4. If equipped, detach the brake warning indicator connector. NOTE: A turkey baster (tapered tube with a squeeze ball on top) works well for removing fluid from the reservoir (see photo).
  5. Siphon off the fluid from the master cylinder reservoir to minimize spillage when lines are disconnected.
  6. If applicable, disconnect and cap the Hydraulic Control Unit (HCU) supply hose at the master cylinder reservoir and secure in a position to prevent loss of fluid.
  7. Unfasten the 2 nuts and lockwashers that attach the master cylinder to the brake booster.
  8. Remove the master cylinder from the booster by sliding it forward and upward from the vehicle. To install:
  9. Install a new seal in the groove in the master cylinder mounting face.
  10. Position the master cylinder assembly over the booster pushrod and onto the 2 studs on the booster assembly.
  11. Install the retaining nuts, then tighten to 18–25 ft. lbs. (24–34 Nm).
  12. Uncap and connect the brake lines to the master cylinder. Tighten the front fitting to 16–21 ft. lbs. (21–29 Nm), and the rear fitting to 10–15 ft. lbs. (15–20 Nm).
  13. Uncap and connect the HCU hose to the master cylinder reservoir fitting and secure with a hose clamp.
  14. If equipped, connect the brake warning indicator.
  15. Fill the master cylinder with Heavy Duty Brake Fluid C6AZ-19542-AA or equivalent DOT 3 brake fluid from a clean, sealed container. Bleed the entire brake system, as outlined in this section.
  16. Connect the negative battery cable.
  17. Operate the brake several times, then check for external hydraulic leaks.

How to replace master cylinder on 1989 century


You have to Remove the brake lines going to the cylinder, then remove the 2 nuts holding it to the brake booster.

Make sure u bench bleed the new master before you install, the new one should come with a bench bleed kit, u must attach the 2 hoses to both ports on the master cylinder where the brake lines connect to, then run the 2 hoses into the top of the reservor and fill it with fluid, use a screw driver and pump the master cylinder until you can see no air bubbles running through the hoses

How dificult is it to replace a wheel cylinder in a 2000 Jeep.


On a scale of 1-10, its about a 3. It's a bolt out, bolt in item. Remove the brake linings, detach the brake line, using a flair nut wrench to avoid damage. (if frozen, remove line completely & replace. line can be cut above nut and 6pt socket can be used to remove it.). Unbolt cylinder and push it through the backing plate. Reverse process to install. When finished, re-fill master cyl and open bleeder screw on new cyl. push brake pedal down gently with your hand (do not use your foot or push hard...you can damage the master cyl) and keep it down while someone closes the bleeder. Open the r/r bleeder and do same thing. till no air comes out. repeat again at l/r.Close it up, re-fill master and your'e finished. (note: if master was dry before you began repair, re-fill and begin bleeding process at master before bleeding either rear cyl.While bleeding, closely monitor master level so you do not run dry)
Note: It is advised that brqake linings be replaced after any leak. If you cannot afford, wash linings and drum in strong soapy water & dry off before using. not as good as new, but better than oil soaked!
