Emergency Brake Hardware 2003 Jeep Laredo

Welcome to the JeepSpecs.com in-depth page of WJ Generation Jeep Grand Cherokee'south parking brake. Did we mis anything? Please get in touch with us and tell us near it!

The parking brakes operated by a automatic tensioner mechanism built into the hand lever and cable arrangement. The front end cable is connected to the hand lever and the blaster. The rear cables attached to the equalizer and the parking restriction shoe actuator.

A set of drum type brake shoes are used for parking brakes. The shoes are mounted to the rear disc brake adaptor. The parking brake drum is integrated into the rear disc brake rotor.

Diagnosis and testing the parking brake

Annotation: PARKING Brake Adjustment IS CONTROLLED BY AN AUTOMATIC Cablevision TENSIONER AND DOES NOT REQUIRE ADJUSTMENT. THE Just Adjustment THAT MAY BE NECESSARY WOULD BE TO THE PARK Brake SHOES IF THEY ARE WORN, OR WHEN THE SHOES ARE REPLACED, REMOVED FOR ACCESS TO OTHER PARTS, OR WHEN 1 OR BOTH ROTORS ARE REPLACED.

The parking brake switch is in circuit with the red warning lamp in the dash. The switch will crusade the lamp to illuminate only when the parking brakes are applied. If the lamp remains on afterward parking brake release, the switch or wires are faulty.

If the red lamp comes on a fault has occurred in the front or rear brake hydraulic system.

If the reddish alert lamp and yellow alarm lamp come on, the electronic restriction distribution may be at mistake.

In most cases, the actual cause of an improperly functioning parking brake (likewise loose/too tight/won't hold), can exist traced to a parking restriction component.

Notation: THE LEADING Crusade OF IMPROPER PARKING BRAKE OPERATION, IS EXCESSIVE CLEARANCE BETWEEN THE PARKING BRAKE SHOES AND THE SHOE BRAKING SURFACE. EXCESSIVE CLEARANCE IS A Effect OF LINING AND/OR DRUM Article of clothing, Pulsate SURFACE MACHINED OVERSIZE.

Excessive parking brake lever travel (sometimes described as a loose lever or likewise loose condition), is the upshot of worn brake shoes, improper brake shoe aligning, or improperly assembled restriction parts.

A as well loose status can too be caused past inoperative or improperly assembled parking brake shoe parts.

A condition where the parking brakes do not hold, will most probably be due to a wheel restriction component.

Items to wait for when diagnosing a parking brake problem, are:

• Brake shoe wear
• Drum surface (in rear rotor) machined oversize
• Front cablevision non secured to lever
• Rear cable not attached to actuator
• Rear cable seized
• Parking restriction lever not seated
• Parking brake lever demark

Adjustment

Under normal circumstances, the only time adjustment is required is when the shoes are replaced, removed for admission to other parts, or when ane or both rotors are replaced.

Aligning can be made with a standard restriction gauge or with adjusting tool. Adjustment is performed with the complete restriction associates installed on the backing plate.

1. Exist sure parking brake lever is fully released.

2. Raise vehicle then rear wheels tin can be rotated freely.

3. Remove plug from each access hole in brake support plates.

iv. Loosen parking restriction cable adjustment nut until there is slack in front cable.

five. Insert adjusting tool through support plate access hole and appoint tool in teeth of adjusting spiral star wheel.

half dozen. Rotate adjuster spiral star wheel (move tool handle upward) until slight drag tin be felt when wheel is rotated.

7. Push and concur adjuster lever away from star wheel with sparse screwdriver.

8. Dorsum off adjuster screw star wheel until restriction drag is eliminated.

ix. Echo adjustment at opposite wheel. Exist sure adjustment is equal at both wheels.

x. Install support plate access pigsty plugs.

eleven. Adjust parking restriction cable and lower vehicle.

12. Depress park restriction lever and make certain park brakes hold the vehicle staionary.

13. Release park restriction lever.
