My emergeny brake will not hold. I have already spent $150.00 and I still have a problem with my brake holding. The mechanic says that I need new emergency brakes, but he did not even look at the breaks. I...


The parking brake can be "adjusted" from either inside the vehicle or underneath, although adjusting the parking brake AT the brake itself is the correct way to adjust the brakes themselves. The proper procedure would be to adjust the actual brakes, then to test at the pedal or handle (depending upon which vehicle you have). If the handle or pedal has too much "freeplay", THEN the cable or handle/pedal will need to be adjusted.

If you do not use your parking brake on a regular basis, the brake components will usually build rust (if it is a "drum-type" parking brake). This also can prevent the brake from holding properly.

Unfortunately, it is difficult to determine if your mechanic is taking advantage of you without knowing exactly what was done to your vehicle, but I would say if you are not satisfied with your current mechanic, go to a few places and get the parking brake "checked." Ask other mechanics their opinion- after they have inspected the parking brake, do the brakes need service or not? What can be done to improve the parking brake's performance?


One last note, some technicians don't realize that new parking brakes need to be broken in, and any small amount of grease or oil can negatively affect the operation. If you DO wind up needing brakes, try to use your parking brake as often as possible to keep everything working smoothly.

How do I get the rear spindle off so I can replace the emergency brake shoes on my 2006 chrysler pacifica?



Adjustment

  1. Place parking brake lever in -full released- position.
  2. Raise and support vehicle.
  3. Remove plug in parking brake shoe support to access adjuster star-wheel.
  4. Through the access hole, rotate the adjuster star wheel in the following direction to expand the shoes outward against the drum:
    1. Left brake - Rotate star-wheel toward rear of vehicle.
    2. Right brake - Rotate star-wheel toward front of vehicle.
  5. Using an appropriate tool, turn adjuster star wheel until wheel will not rotate (dead lock).
  6. Back off adjuster six detents (teeth).
  7. Rotate wheel, checking for light drag. If drag is too heavy, continue to back off adjuster one detent at a time until light drag is present. Do not back off star-wheel more than 17 detents from wheel lock.
  8. Install access plug.
  9. Adjust opposite wheel parking brake shoes using same method.
  10. Lower vehicle.
  11. Apply and release parking brake lever once to ensure proper operation of parking brakes.


Removal & Installation NOTE The following procedure may be used to remove shoes on either side of the vehicle.

  1. Lock out automatic adjuster in parking brake lever.
  2. Raise and support vehicle.
  3. Access and remove rear hub and bearing.
  4. Remove parking brake cable bolt at knuckle.
  5. Completely back off parking brake shoe adjustment.
  6. Remove parking brake shoe adjuster spring.
  7. Remove shoe adjuster.
  8. Remove upper brake shoe hold-down clip and pin.
  9. Remove lower brake shoe hold-down clip and pin.
  10. Remove upper and lower shoes with return spring from shoe actuator.
  11. Remove return spring from shoes.

Rear brakes for toyota 89 how do i get drum off


The drums on this car are usually fairly difficult to remove since it is difficult to see the parking brake adjuster.
Make certain that the parking brake is released.
Following is the recommended procedure:
When the brake drum cannot easily be removed, perform the following steps.
1. Insert a bent wire or something similar through the hole on the brake drum, and hold the automatic adjusting lever away from the adjuster
2. Using a screwdriver, reduce the brake shoe adjustment by turning the adjuster.

How to adjust parking brake. do you need to take anything apart?


You cannot adjust the cables on a minivan manually. the tension is automaitcally adjusted by the self adjuster on the pedal release.

The park brake cables on this vehicle have an automatic self adjuster built into the park brake pedal mechanism. When the foot operated park brake pedal is in its released (upward most) position, a clock spring automatically adjusts the park brake cables. The park brake cables are adjusted (tensioned) just enough to remove all the slack from the cables. The automatic adjuster system will not over adjust the cables causing rear brake drag.

Due to the automatic adjust feature of the park brake pedal, adjustment of the parking brake cables on these vehicles relies on proper drum brake.

When the park brake pedal is applied the self adjuster is by-passed and the pedal operates normally to engage the park brakes.

When a service procedure needs to be performed on the park brake pedal or the park brake cables, the automatic self adjuster can be manually locked out by the service technician.

2006 Pacifica emergency brake problem.


The only manual adjustment for the parking brake on these is at the shoes themselves. Procedure for that is as follows:

1) Place parking brake lever in "full released" position.
2) Raise and support vehicle.
3) Remove plug in parking brake shoe support to access adjuster star-wheel.
NOTE: Through the access hole, rotate the adjuster wheel in the following direction to expand the shoes outward against the drum.
Left brake--Rotate star wheel toward rear of vehicle.
Right brake--Rotate star wheel toward front of vehicle.
4)Using an appropriate tool, turn adjuster star wheel until wheel will not rotate (dead lock).
5) Back off adjuster six detents (teeth).
6) Rotate wheel, checking for light drag. If drag is too heavy, continue to back of adjuster one detent at a time until light drag is present. Do not back off star-wheel more than 17 detents from wheel lock.
7) Install access plug.
8) Adjust opposite wheel parking brake shoes using same method.
9) Lower Vehicle.
10) Apply and release parking brake lever once to ensure proper operation of parking brakes.

These directions are directly from 2006 Pacifica factory service manual.

PARKING BRAKE NOTE: Tensioner adjustment is only necessary when the tensioner, or a cable has been replaced or disconnected for service. When adjustment is necessary, perform adjustment only as described in the following procedure. This is necessary to avoid faulty park brake operation.
  1. Raise vehicle.
  2. Fully back off cable tensioner adjusting nut at equalizer to create slack in cables.
  3. Remove rear wheel/tire assemblies. Remove brake calipers and rotors.
  4. Verify park brakes are in good condition and operating properly.
  5. Verify park brake cables operate freely and are not binding, or seized.
  6. Check park brake shoe adjustment.
  7. Reinstall rotors and make sure rotors turn freely.
  8. Reinstall brake calipers. Tighten guide pin bolts to 41 n·m (30 ft.lbs.)
  9. Reinstall wheel/tire assemblies after brake shoe adjustment is complete.
  10. Lower vehicle enough for access to park brake foot pedal. Fully apply park brakes
NOTE: Leave park brakes applied until adjustment is complete.
  1. Raise vehicle again.
  2. Mark tensioner rod 6.35 mm (1/4 in.) from edge of tensioner bracket Adjustment Mark On Cable Tensioner Rod
  3. Tighten adjusting nut at equalizer until mark on tensioner rod moves into alignment with tensioner bracket
CAUTION: Do not loosen, or tighten the tensioner adjusting nut for any reason after completing adjustment.
  1. Lower vehicle until rear wheels are 15-20 cm (6-8 in.) off shop floor.
