Land Rover Part Number: LR048138 - Brake Master Cylinder
LR048138 is a Brake Master Cylinder. Fitted to Range Rover L405 models, it converts driver pedal input into hydraulic pressure for the vehicle's braking system. The unit houses the primary piston assembly and fluid reservoir; when the pedal is applied the piston moves in a precision bore to force brake fluid through seals and ports into the brake lines to operate calipers and wheel cylinders. The master cylinder interfaces with the pedal pushrod and brake fluid reservoir and must be free of internal leaks or bore damage; when replacing, ensure the correct master cylinder is selected for the vehicle's engine and ABS/ESC configuration to maintain correct brake balance and pedal feel.

Frequently Asked Questions
The LR048138 master cylinder produces and distributes hydraulic pressure when the brake pedal is applied, using a primary piston and reservoir to feed fluid into the front and rear hydraulic circuits. Common failure modes include internal leaks or bore damage that cause reduced pressure or a spongy pedal; when replacing, match the unit to the vehicle's engine and ABS/ESC configuration to preserve correct brake balance and pedal feel.
