Volvo V70 models are equipped with a mechanical parking brake. This parking brake is used to hold the vehicle stationary when not in use. The parking brake is operated via a handle in the vehicle cabin. The brake handle pulls attached cables that engage the parking brake shoes. It is a shoe and drum style brake.

The system is compact and integrated into the rear brake rotor system. 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, and the wheels removed. 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 your parking brake lever makes 10 clicks or more, it needs to be adjusted. Keep in mind, the parking brake is not strong enough to brake the vehicle when driven or when being moved by the engine.

Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users.

The system is compact and integrated into the rear brake rotor system (red arrow).
Figure 1

The system is compact and integrated into the rear brake rotor system (red arrow). 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, and the wheels removed.

Jack the rear of your vehicle and remove the wheels.
Figure 2

Jack the rear of your vehicle and remove the wheels. Using a flathead screwdriver working through the adjuster access hole (red arrow), lever down (screwdriver handle will go upward) to loosen the adjuster and back it off the brake drum.

Rotate the brake rotor to be sure it is free from the parking brake shoes.
Figure 3

Rotate the brake rotor to be sure it is free from the parking brake shoes. Repeat this step for the opposite side of the vehicle.

Using a long, thin flathead screwdriver, rotate the adjuster to expand the parking brake shoes until the rotor cannot be turned and then back the adjustment off eight notches.
Figure 4

Using a long, thin flathead screwdriver, rotate the adjuster to expand the parking brake shoes until the rotor cannot be turned and then back the adjustment off eight notches. Lever the adjuster up (green arrow) to expand the brake shoes. The screwdriver handle moves downward.

Working in the vehicle interior, open the center console storage compartment.
Figure 5

Working in the vehicle interior, open the center console storage compartment. Lever the plastic cover out of the bottom of the compartment (red arrow).

With the plastic cover removed, you now have access to the parking brake cable adjuster (red arrow).
Figure 6

With the plastic cover removed, you now have access to the parking brake cable adjuster (red arrow).

Rotate the adjuster toward the right side (green arrow) of the vehicle to tighten the cables and to the left side to loosen the cables (red arrow).
Figure 7

Rotate the adjuster toward the right side (green arrow) of the vehicle to tighten the cables and to the left side to loosen the cables (red arrow). Pull the parking brake lever multiple times. Release the lever and confirm that the wheels rotate freely. Release the lever and then pull up four notches. Check that the rear wheels do not rotate and the parking brake warning light is ON. See step 10 for the possible second location of the adjuster nut.

If the parking brake light is not working properly, you can inspect the switch.
Figure 8

If the parking brake light is not working properly, you can inspect the switch. Start by using a plastic prying tool to lever the parking brake handle trim toward the left side of the vehicle (red arrow).

Remove the trim from the center console.
Figure 9

Remove the trim from the center console.

The parking brake switch (red arrow) is a single wire switch that is grounded when the parking brake is engaged.
Figure 10

The parking brake switch (red arrow) is a single wire switch that is grounded when the parking brake is engaged. You can test it by unplugging it. The light should go out. Or by grounding the wire, the light should go on. Some models may have an adjuster for the parking brake cable located at the front of the handle (green arrow). This style can be a 10mm or 11mm lock nut that requires tightening.
