Land Rover Part Number: RTC3658 - Metric Thread Brake Master Cylinder
RTC3658 is a metric-thread brake master cylinder fitted to the braking system on Range Rover Classic vehicles up to VIN HA610293. It converts mechanical pedal input into hydraulic pressure to operate wheel cylinders and calipers, matching the original thread form and port positions for direct installation. The assembly contains primary and secondary pistons to pressurise separate front and rear circuits, includes a reservoir connection to maintain fluid supply and compensate for pad wear, and provides external ports that interface with brake lines and any fitted servo or proportioning valve; the pushrod connection links the pedal to the internal piston mechanism. Correct thread form and port orientation are essential to prevent leaks and to maintain correct pushrod geometry where a servo is present.
