Specialized drum brake service in Tallinn
Drum brakes are often used on the rear axle of compact cars, commercial vehicles, electric cars and as a drum-in-hat parking brake mechanism inside rear brake discs. Stable operation depends on the brake shoes, drums, wheel cylinders, springs, self-adjusters and parking brake cables.
Mr.Car performs drum brake diagnostics and repair for Volkswagen, Skoda, Audi, Toyota, Hyundai, Kia, Ford, Renault, Dacia and other makes. We replace brake shoes and drums, repair leaking wheel cylinders, service return springs and self-adjusters, adjust the parking brake and replace DOT4 brake fluid.
Before replacing parts, we open and inspect the mechanism, measure drum wear, check the friction material thickness, look for brake fluid leaks and corrosion, and agree on the repair scope before work starts.
Common drum brake symptoms
A leaking wheel cylinder, stuck self-adjuster or contaminated brake shoes can reduce rear braking performance even when the front brakes feel normal.

Parking brake and drum-in-hat mechanisms
Some vehicles use a separate small drum mechanism inside the rear brake disc only for the parking brake. This is common on several Audi, BMW, Mercedes-Benz and Volvo models.
If the parking brake does not hold on a slope, the issue may be worn inner shoes, a seized expander, a stretched cable or incorrect adjustment. We inspect the mechanism and avoid replacing parts that are still serviceable.
Drum brake repair FAQ
When should drum brake shoes be replaced?
Drum brake shoes usually last around 60,000-80,000 km, but the mechanism should be inspected every 30,000-40,000 km or every two years. We check shoe thickness, drum wear, wheel cylinders, springs and self-adjusters.
Why does the parking brake hold poorly?
Typical causes are a stretched parking brake cable, incorrect shoe-to-drum clearance or a stuck self-adjuster. Often the mechanism can be cleaned and adjusted without replacing good shoes.
Can I drive with a leaking wheel cylinder?
No. Brake fluid on the friction material sharply reduces braking efficiency and can create dangerous imbalance between the wheels. The cylinder must be replaced, and contaminated shoes usually need replacement.
Why do EV drum brakes need regular service?
Because regenerative braking means the rear mechanical brakes may work less often. Moisture and corrosion can build up inside the drum, so yearly preventive inspection is recommended.
