How do I change the brake master cylinder on a 2000 dodge dakota rt 360 magnum 5.9l v8 mopar


disconnect the front and rear brake lines, undo bolts holding the master cylinder to the brake booster. Bench bleed the new master and reconnect to booster and reconnect lines. Be very careful when undoing the lines from the master cyclinder as you do not want to damage them. Soak with WD-40 before loosening. Once everything is back in place you will need to bleed all calipers and/or wheel cylinders. Again soak the bleeder screws beforehand with WD-40 as they break off easily.

Bleed breaks pedal still spongy


On these old manual brake systems without automatic adjusters you have to set the shoe clearance by turning the adjuster on each shoe out so the shoe is very close to the drum. If there is too much clearance between the shoe and drum the shoe will move as far as it can and never touch the drum, this will make a low or no pedal pressure.

1990 jeep wrangler bleeding breaks


Hi there:
I suggest to check this procedure, when the hydraulic brake system must be bled whenever a fluid line has been disconnected because air gets into the system.

A leak in the system may sometimes be indicated by a spongy brake pedal. Air trapped in the system is compressible and does not permit the pressure applied to the brake pedal to be transmitted solidly through the brakes. The system must be absolutely free from air at all times. If the master cylinder has been overhauled or a new cylinder has been installed, bleed the cylinder on a bench before installation. When bleeding brakes, bleed at the wheel most distant from the master cylinder first, the next most distant second, and so on. During the bleeding operation the master cylinder must be kept at least 3 / 4 full of brake fluid.


The ABS bleeding procedure is different from the conventional method. It consists of the following three steps:
Step 1: Conventional manual brake bleed.
Step 2: Bleeding the system using the DRB scan tool.
Step 3: An additional conventional manual brake bleed.

The recommended ABS bleeding procedure is as follows:
  1. To bleed the brakes, first carefully clean all dirt from around the master cylinder filler cap. Remove the filler cap and fill the master cylinder with DOT 3 brake fluid to the lower edge of the filler neck.
  2. Bleed the master cylinder first. Have a helper operate the brake pedal while bleeding each master cylinder fluid outlet line. Do not allow the master cylinder to to run out of fluid,as this will allow additional air to be drawn into the cylinder.
  3. Bleed the brake system in the following sequence:
    1. Master cylinder
    2. HCU valve body (at fluid lines)
    3. Right rear wheel
    4. Left rear wheel
    5. Right front wheel
    6. Left front wheel
  4. Clean off the bleeder connections at all four wheel cylinders. Attach the bleeder hose to the right rear wheel cylinder bleeder screw and place the end of the tube in a glass jar, submerged in brake fluid.
  5. Open the bleeder valve 1/2 - 3/4 of a turn.
  6. Have an assistant depress the brake pedal slowly and allow it to return. Continue this pumping action to force any air out of the system. When bubbles cease to appear at the end of the bleeder hose, close the bleeder valve and remove the hose.
  7. Check the level of fluid in the master cylinder reservoir and replenish as necessary.
  8. After the bleeding operation at each wheel cylinder has been completed, fill the master cylinder reservoir and replace the filler plug.

Do not reuse the fluid which has been removed from the lines through the bleeding process because it contains air bubbles and dirt.


  1. Perform the "Bleed Brake'' procedure with the DRB II scan tool. This procedure is described in the DRB II software information and diagnostic guide.
    1. Attach the DRB II scan tool to the diagnostic connector.
    2. Run the Bleed Brake procedure as described in the DRB II tester guide.
  2. Repeat the conventional bleeding procedure as previously outlined.
  3. Fill the master cylinder reservoir to the proper level.
  4. Check the brake operation.


Hope this helps.

Brake pedal to floor have replaced brake pads and master cylinder


Did the pedal go to the floor beforehand? Was the master cylinder leaking, and did you bleed it properly? If the master cylinder was not leaking, check your brake lines going to the rear wheels.

1996 chevy blazer 4wd break petal goes all the way to the floor breaks r good new master cylinder blead all braks 10 times any sugesstins? help!!!


I know there is ABS in that vehicle, you might still have air in the ABS unit, you will need to get a manual that shows you the correct procedure to bleed the brakes. Master installed u need to start the bleed on the bench, then move to the ABS unit then to the individual calipers and/or wheel cylinders if equipped. I think there is a certain way to do it to avoid incorrect bleeding.

But i have also seen bad master cylinders brand new in the box.

Good Luck.

I seem to have a problem with my hydro breaking system.Found front worn out while the rear shoes were covered with oil and had not been working for some time.After replacing calipers,rotors,shoes and wheel...


ALL YOU CAN DO IS FLUSH WITH CLEAN FLUID PUMP AND BLEED NOTE: ALWAYS START FROM THE FURTHEST WHEEL FROM THE MASTER CYLINDER AND WORK YOU WAY BACK. SOME TIMES YOU CAN OPEN THE LINES WITH COMPRESSED AIR WHEN YOU DISCONNECT ALL THE LINES FROM THE CYLINDERS

If you want to change break master cylinder,first remove two break pipes then remove four nuts which is holding master cylinder to breake booster.careful breake fluid from the car body and your self.

put the new breake master cylinder tight four nuts, before you fit the braeke pipes get some body who can hold breake bedel down put the breake fluide tell him to pump breake bedel when the brake master take fluid hold your fingers where you want to fit brake pipes when you feel more pressure which is pushing your finger tell him to hold the bedel down while you tighting the pipes.
you dont need to bleade the wheels. it is ready.
the ather thing when you remove the breake master put the new one then fit the brake pipes fil with the breake fluide then bump so you must bleade all wheels
