LHM master cylinder overhaul kit (from 1983)

Restore your classic car's braking performance with this LHM master cylinder rebuild kit.

This kit restores the master cylinder's sealing without replacing the cylinder body. Over time, the rubber seals wear out, causing pressure loss or leaks of the green LHM hydraulic fluid. These components act on the hydraulic circuit pressurizing mechanism to ensure reliable braking.

With this kit, simply replace the old seals and cups with the new parts provided. Clean the inside of the cylinder before reassembly and lubricate the components with LHM fluid to ease installation and protect the rubber during the initial pressurization.

. Material : rubber resistant to LHM mineral hydraulic fluid (not compatible with DOT 4 synthetic brake fluid)
. Hydraulic system : dual-circuit hydraulic system for models equipped with front disc brakes
. Engine : 602 cc engine
. Quantity : 1 kit per vehicle
