Rear brake shoes of the rear drum brake mechanism — replacement (Opel Zafira A)

The necessity of performing this operation should be determined during the process of checking the technical condition of the brake system (see "Brake system - checking technical condition").

Warning! When the brake pistons are pressed into the cylinders, the brake fluid level in the reservoir will increase, so pump out some of the brake fluid from the reservoir. After replacing the brake pads, check the brake fluid level and, if necessary, bring it up to normal (see "Checking the levels of technical fluids").

If the brake pads are worn on only one side, it is necessary to replace the pads on both sides of the vehicle.

Recommendation: When replacing brake pads, be sure to check the degree of wear and condition of the brake drum (see "Rear drum brakes - check").
