Brake Light Switch Problems

Several front disc brake model bikes have a release button type switch snuggly mounted under the lever bracket, offering no adjustment. When levers wear a little and start to slop at idle, the brake light can often flicker in unison or remain on as the stopper bar is out of alignment to the tiny button head. To stop this problem without having to source a new lever and bracket, slip a valve cap over the stopper bar. The cap can be easily shaved down with a blade on one side to allow any adjustments.

how do i adjust emergency brake cable on 2003 jeep liberty sport. qith 4 disc brake pads.


Remove rear wheels and the brake rotors. parking/Emegency brake shoes are inside these rotors. Check shoes if worn, replace them Your Emergency brake is self adjustable.

OPERATION
A hand operated lever in the passenger compartment is the main application device. The front cable is connected between the hand lever and the rear cables with an equalizer.

The rear cables are connected to the actuating lever on each primary brake shoe. The levers are attached to the brake shoes by a pin either pressed into, or welded to the lever. A clip is used to secure the pin in the brake shoe. The pin allows each lever to pivot independently of the brake shoe.

To apply the parking brakes, the hand lever is pulled upward. This pulls the rear brake shoe actuating levers forward, by means tensioner and cables. As the actuating lever is pulled forward, the parking brake strut (which is connected to both shoes), exerts a linear force against the secondary brake shoe. This action presses the secondary shoe into contact with the drum. Once the secondary shoe contacts the drum, force is exerted through the strut. This force is transferred through the strut to the primary brake shoe causing it to pivot into the drum as well.

A gear type ratcheting mechanism is used to hold the lever in an applied position. Parking brake release is accomplished by the hand lever release button.

A parking brake switch is mounted on the parking brake lever and is actuated by movement of the lever. The switch, which is in circuit with the red warning light in the dash, will illuminate the warning light whenever the parking brakes are applied.

Parking brake is self-adjusting when the lever is pulled. The cable tensioner, once adjusted at the factory, should not need further adjustment under normal circumstances.
REMOVAL
  1. Raise and support the vehicle.
  2. Remove the tire and wheel assembly.


  1. Remove the disc brake caliper.
  2. Remove the disc brake rotor.
Brake Shoe

  1. Disassemble the rear park brake shoes.
CLEANING - REAR DRUM IN HAT BRAKE
Clean the individual brake components, including the support plate exterior, with a water dampened cloth or with brake cleaner. Do not use any other cleaning agents. Remove light rust and scale from the brake shoe contact pads on the support plate with fine sandpaper.

INSPECTION - REAR DRUM IN HAT BRAKE
As a general rule, riveted brake shoes should be replaced when worn to within 0.78 mm (1/32 inch) of the rivet heads. Bonded lining should be replaced when worn to a thickness of 1.6 mm (1/16 inch) .
Brake Shoe

Examine the lining contact pattern to determine if the shoes are bent or the drum is tapered. The lining should exhibit contact across its entire width. Shoes exhibiting contact only on one side should be replaced and the drum checked for runout or taper.

Inspect the adjuster screw assembly. Replace the assembly if the star wheel or threads are damaged, or the components are severely rusted or corroded.

Discard the brake springs and retainer components if worn, distorted or collapsed. Also replace the springs if a brake drag condition had occurred. Overheating will distort and weaken the springs.

Inspect the brake shoe contact pads on the support plate, replace the support plate if any of the pads are worn or rusted through. Also replace the plate if it is bent or distorted.

INSTALLATION

NOTE: On a new vehicle or after parking brake lining replacement, it is recommended that the parking brake system be conditioned prior to use. This is done by making one stop, from 25 mph on dry pavement or concrete using light to moderate force on the parking brake lever.

  1. Reassemble the rear park brake shoes.
  2. Adjust the rear brake shoes.
  3. Install the disc brake rotor.
  4. Install the disc brake caliper.
  5. Install the tire and wheel assembly.
  6. Lower the vehicle.

parking brake light won't go off after releasing brake lever


Park brake lights normally operate by a small plunger type switch the turns off when the level or pedal is placed in the off position. Over time the spring in the lever weakens and placing the lever in the off position no longer depresses the switch. The switch can sometimes be adjusted to make better contact, or the switch bracket can be bent so the lever and switch make proper contact.

Im pretty sure the handbrake cable on my 2004 Jetta has broken, is this an easy fix or should i consult a mechanic?


here is the procedure from autozone.com. there are no special tools, but you need to be handy. Judge for yourself.


Removal & Installation

  1. Raise and safely support the rear wheels.
  2. On Front Wheel Drive models, remove the heat shield above the exhaust in the center tunnel.
  3. Locate the threaded adjusters. On All Wheel Drive (AWD) models, they are located in the front of the lower control arms, on Front Wheel Drive (FWD) vehicles, they are located in the tunnel on the underbody of the vehicle.
  4. Remove the locking clip between the hex nut and the adjustment housing.
  5. Counter hold the hex nut with a 13mm wrench and thread the adjustment housing to loosen the cable until the adjustment housing is fully loosened, then slide the 2 portions of the cable toward one another.
  6. Remove the lock clip at the brake caliper and remove the cable, taking care to not damage the cable boot.
  7. On Front Wheel Drive models, remove the heat shield above the muffler and push aside.
  8. Remove the cables from the cable brackets. Should the assembly aid fall out it is not necessary to reinstall it.
  9. Using a suitable flat blade screwdriver, remove the cables from the retaining bracket at the under body tunnel where the cables enter the interior of the vehicle.
  10. Remove the rear portion of the center console, then using a suitable flat blade screwdriver, push the cables toward the parking brake lever and press the cable ball end out of the bracket.
  11. From under the vehicle, press the guide sleeve-locking element together and pull the cables out of the guide sleeve.
To install:
  1. Guide the parking brake cables through until the guide sleeve locks into place.
  2. If not previously removed, remove any plastic parts at the hand brake lever adjustment bracket as they are not needed for installation.
  3. Using a No. 2 flat-blade screwdriver, lock the adjustment bracket at the hand brake lever to prevent it from turning.
  4. Insert the cable end ball through the mounting in the adjustment bracket, making sure the cable locks into place in the bracket.
  5. Working under the vehicle, route the cables through their routing brackets and attach them to the brake caliper.
  6. The balance of installation is in reverse order of removal noting the following:
  7. Adjust the parking brake cable and check its operation.
Disc Brakes
  1. Raise and safely support the vehicle.
  2. Release the parking brake. It may be necessary to unscrew the adjusting nuts to provide slack in the brake cable.
  3. At each rear wheel brake caliper, remove the spring clip retaining the parking brake cable to the caliper.
  4. Lift the cable from the caliper mount and disengage it from the parking brake lever.
  5. Pull the cables out from under the vehicle.
  6. Installation is the reverse of removal.
  7. Adjust the parking brake as described at the beginning of this section.
Drum Brakes
  1. Block the front wheels and release the hand brake.
  2. Raise and safely support the rear of the vehicle.
  3. Remove the rear brake shoes.
  4. Remove the brake cable assembly from the back plates.
  5. Remove the cable adjusting nuts at the handle and detach the cable guides from the floor pan.
  6. Pull the cables out from under the vehicle.
  7. Installation is the reverse of removal. Adjust the parking brake and road test the vehicle.
