Brake fluid inside the drum
A wet wheel cylinder or contaminated lining needs prompt repair, not just topping up the reservoir.
Rear drum-brake leak diagnosis
Brake Wheel Cylinder Replacement in South London
A leaking or seized wheel cylinder can reduce rear-brake performance and contaminate the brake shoes. SP88 inspects the drum assembly and hydraulic system before quoting the complete repair.
When to arrange an inspection
Low or soft brake pedal
Hydraulic leakage or air in the system can increase pedal travel and reduce braking confidence.
Uneven rear braking
A seized piston, worn shoes, adjustment fault or handbrake problem can pull or imbalance the brakes.
MOT brake imbalance
The cylinder is one possible cause; shoe condition, drum wear and adjustment are checked too.
How SP88 approaches the fault
We inspect for hydraulic leakage, check the drum, shoes, springs and adjuster, and confirm the correct cylinder. The system is bled after replacement and the rear brake operation is checked. If fluid has soaked the linings, affected shoes and related hardware may also need replacement.
Service boundary: Brake repairs are quoted from the actual condition. Depending on wear and contamination, work may be required on both sides of the axle to restore balanced braking.
Safety comes first
Do not drive with a low pedal, visible brake-fluid leak or rapidly falling reservoir level. Arrange recovery because braking performance can deteriorate without warning.
SP88 covers Wallington, Sutton, Croydon, Purley and nearby South London and Surrey areas. Suitability for mobile work depends on the vehicle, access and the confirmed repair.
