Master Cylinder Inspection
Although the mechanics of modern master cylinders seem deceptively simple, today’s dual-piston or tandem master cylinders still require the utmost in care and attention to maintain safe, reliable operation. The tandem master cylinder contains two piston assemblies; one for each axle set or diagonally located pair of brakes. Each piston assembly has two lip seals
Brake & Suspension System Service
Brake and suspension repairs are the best type of routine maintenance repairs that coincide with major service intervals. Brake and suspension components that are in need of replacement could represent a significant profit center for shops when technicians take the time to perform complete chassis inspections.
