Complementary Modification:

Flush brake fluid. Replace brake rotors and pads

The parking brake is a drum system that is integrated into the rear brakes. The rear rotor hub flange acts as the drum and the brake shoes are mounted to the backing plate. The parking brake shoes can fail, linings can fall off and create a grinding noise. The hole where the retaining clips mount can also rust and fail. When this happens, the retaining clips pull through and parking brake shoes come in contact with brake rotor when driving. If this happens, you will need to replace the backing plate, brake shoes, hardware and rotor.

Loosen wheels studs while vehicle is on ground, do not remove. Lift and support rear of vehicle. See our tech article on jacking up your vehicle.

Remove rear wheels.

Working in vehicle interior, lever bottom of parking brake lever up using a plastic prying tool.

Then pull up parking brake lever boot to detach from center console.

Check that parking brake lever is in released position.
Figure 3

Check that parking brake lever is in released position. Then release cable tension by engaging service lock. Press spring with flathead screwdriver until hook locks spring in compressed position. If parking brake lever is not fully released, you will not be able to engage service lock (green arrow)

Using a long flathead screwdriver, engage parking brake service lock.

Using a long flathead screwdriver, engage parking brake service lock. A small hook will grab and hold spring once properly engaged. (green arrow)

Using a flathead screwdriver, slowly press brake caliper piston in.
Figure 5

Using a flathead screwdriver, slowly press brake caliper piston in. This allows brake caliper to be pulled off brake rotor easily. I like to pry between the outer brake pad and brake rotor. This way there is less chance of damaging the caliper piston.

Working behind brake caliper: Remove two 16mm brake caliper bracket mounting bolts.

Next, using a 6mm Allen bit, remove brake rotor mounting fastener.

Next, unhook lower return spring from parking brake shoes.
Figure 8

Next, unhook lower return spring from parking brake shoes. (green arrow) I like to use an old pair of diagonal cutters, with worn out cutting jaws. Grab the spring, pull it down and unhook from brake shoe.

Using a long 5mm Allen bit, remove parking brake shoe retaining clips by rotating 90° and pulling away from brake shoes.

Using a long 5mm Allen bit, remove parking brake shoe retaining clips by rotating 90° and pulling away from brake shoes. Each shoe has one clip. (green arrow)

Remove parking brake shoes from vehicle, then separate remaining parts.

Inspect shoe adjuster, check that it moves freely and is not damaged.

Then lightly grease brake shoe to backing plate contact points.
Figure 12

Then lightly grease brake shoe to backing plate contact points. (green arrows) This photo shows front contact points. Apply grease to area for rear parking brake shoe also. Install new brake shoes in reverse order of removal. Install brake rotor and brake caliper. Adjust parking brake once wheels are installed and tightened. See our tech article on parking brake adjusting.

Comments and Suggestions:
Bryant S. Comments: Good tip on the diagonal cutters or pliers. They are really helpful when re-installing the springs. I wished I had them when I did mine.

  Followup from the Pelican Staff: Yeah, works great. As long as they are dull and you are careful not to snip the spring. - Nick at Pelican Parts  
Mike B Comments: My son had new rear discs and pads fitted at a garage last year and his handbrake hasn't worked properly since. He doesn't seem bothered but I'm going to have a go at sorting it by following your excellent guide. I'm confident that I'll get it working properly. I'll let you know how I get on.

  Followup from the Pelican Staff: let us know how it works out. - Nick at Pelican Parts  
JJ Comments: Do you think that a loose parking brake or unattached parking brakes would cause abs sensors lights to come on?

  Followup from the Pelican Staff: Not likely. - Casey at Pelican Parts  
UptownEvo Comments: Jay r - Some dumb dumb at an indy shop put front rotors on my rear. front has two sizes the exact same thing happened to me - spun the star wheel right off trying to get the pads to "grip" After buying the right size rotor and close inspection, the front rotor they used has a wider interior circumference., thus not allowing the parking brake pads to hit the rotor. Put the right parts on, tightened the star wheel and it holds. Sounds like you might have the wrong part number. Even if you ordered the correct ones, they may have sent the wrong ones. good luck

  Followup from the Pelican Staff: Thanks for the info, bummed you had to deal with that. - Nick at Pelican Parts  
jay r Comments: here is the picture of the changed shoes

  Followup from the Pelican Staff: The rotor may be worn, or you have the wrong parts. - Nick at Pelican Parts  
jay r Comments: thanks, i changed the shoes and expanded the shoes as far as possible using the starwheel. Still it does not hold the rotor, the rotor turns freely with no grip from the shoes. I even broke the star wheel on the other side expanding it to the utmost expansion but couldn't get the shoes to hold the rotor in place. Any suggestions for a fix?

Cheffery. Comments: Hi Guys,
You see in Fig. 12 under the Lowest green arrow there is a Cast "stay" that the Shoes contact and the handbrake actuating lever rides on for some reason on my car there is a channel worn into this form a Parking brake Failure at some time in the cars life.
It seems to make the Parking brake "slip" and tears out the shoe retaining pins.
Is it part of the Hub Assembly?

Could a repair be done to make good?

  Followup from the Pelican Staff: There may be a part available, repairing sounds unlikely. Can you share a photo of the worn part? Give our parts specialists a call at 1-888-280-7799. They can help you find the right part.
