Aftermarket: Quality alternative. This is a quality alternative, designed to fit and function like the original part, often at a more competitive price.
Master Cylinder Reservoir Cap seals the fluid reservoir on the brake or clutch master cylinder.

It screws or presses onto the reservoir neck to retain the hydraulic fluid and keep dirt and moisture out of the system, while allowing the reservoir to vent so the fluid level can rise and fall as the brakes or clutch operate and the friction material wears.

Replace a cracked, perished or poorly sealing cap to prevent fluid contamination and loss.

Frequently asked questions

What does the master cylinder reservoir cap do?
The master cylinder reservoir cap seals the fluid reservoir on the brake or clutch master cylinder. It screws onto the reservoir neck to hold the hydraulic fluid in and keep dirt and moisture out, while venting so the fluid level can drop as the brakes or clutch wear. Fits Land Rover Series and Defender.
Which Land Rover models use this reservoir cap?
This master cylinder reservoir cap fits the Land Rover Series 3 and Defender. Because reservoir necks varied across years and master cylinder suppliers, compare your old cap's thread and diameter before ordering. It suits both brake and clutch master cylinder reservoirs of the matching type.
When should the reservoir cap be replaced?
Replace the master cylinder reservoir cap once it's cracked, perished or no longer sealing cleanly. A poor seal lets moisture into the brake or clutch fluid, which lowers its boiling point and invites contamination. A cap that won't vent properly can also disturb the fluid level as the system operates.
