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.

SOURCE: Brake problem spongy brake pedal pedal goes down

try bleeding them more,start with the right rear,then left rear,then right front ,then left front, always bleed the brake that is furthest from the master cylinder, sometimes you have to bleed them several times until you get a steady stream of brake fluid.

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.

Soft pedal on 03 grand caravan


Have you driven it since the brakes where replaced?

Did you bleed all four wheels?

have you "broken in" the new pads?

Are the rears drum or disk? If drum are they adjusted correctly?

are you using remanufactured master cylinders? If so keep replacing them. eventually you will get one that works. New is pricey but a better way to go.

Brakes are spongy


Did you also bleed the rear brakes? Also try the gravity bleed method working from the right rear wheel, then left rear, right front, then left front. Be SURE to keep the master cylinder full at all times while bleeding.

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.

Brake pedal goes to floor,replaced front pads rear good,bleed brakes no help


Hi:
If you have replaced all pads, and see no leaks at any wheel, and have bled your brake system, then most likely your brake master cylinder has failed.
