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. You can adjust your parking brake with the wheels raised off the ground. You do not have to remove the wheels. A quick check of the parking brake is to pull up the parking brake lever and listen to the number of clicks it makes until stopping. If you're parking brake lever makes 10 clicks or more, it needs to be adjusted. The parking brake can only be adjusted correctly if the cables and all moving parts of the system move easily and function normally.

Working in the vehicle's interior, lever the top of the parking brake lever up using a plastic prying tool.

Then pull up the parking brake lever. Now carefully put forward pressure on the upper part of the released boot to clear the tab. Then pull the boot up and over the parking brake handle.

Check that the parking brake lever is in a released position.

Check that the parking brake lever is in a released position. Then release the cable tension using a 6mm deep socket to back off the 6mm locking nut and a 12 mm deep socket to back off the 12mm adjusting nut (green arrows). Remove one wheel stud per rear wheel while the vehicle is on the ground. Lift and support the rear of the vehicle. See our tech article on jacking up your vehicle.

Rotate the rear wheel until you can see the parking brake adjuster when looking through the hole of the removed wheel stud (green arrow).

Using a long thin flathead screwdriver, rotate the adjuster to expand the parking brake shoes until the wheel cannot be turned.
Figure 5

Using a long thin flathead screwdriver, rotate the adjuster to expand the parking brake shoes until the wheel cannot be turned. Then back off the adjuster 12 notches. For the driver side wheel, lever the adjuster toward the rear of the vehicle. For the passenger side wheel, lever the adjuster toward the front of the vehicle. You can move the adjuster left or right to loosen or tighten the parking brake adjuster. Once you adjust both rear parking brake shoe adjusters, while back inside the car pull the brake handle up two notches. Then tighten the 12mm adjusting nuts until the braking action just begins. Release the brake lever; check that the wheels turn freely. Now tighten the 6mm locking nut with the 6mm deep socket holding the 12mm nut with a 12mm open end wrench. Working in the vehicle interior, pull and release the parking brake lever multiple times. Release the lever and confirm that the wheels rotate freely. Then pull up the parking brake handle five notches. Check that the rear wheels do not rotate and that the parking brake warning light is ON. When done, install the parking brake lever boot and rear wheels studs.

MikeQ Comments: Hi there great write up.
However one query regarding the rotation direction of the adjusters.
When you refer to the "Drivers" side do you mean the left or the right when you are sitting in the car looking forward?
Your handbrake is on the opposite side to mine.
Thanks
