Rear Brake Pressure Reducing Load Proportioning Valve – Volvo 240 / 244 / 245 / 265 (Without ABS)
Part Numbers: 1228738, 1229148

Product Overview:
This is a rear brake load-sensing proportioning valve designed for Volvo 240 series vehicles without ABS. Installed at the rear axle, it plays a crucial role in balancing brake pressure between the front and rear brakes, improving overall vehicle stability during braking.

By reducing brake line pressure to the rear calipers, this valve helps prevent rear-wheel lockup and fishtailing, particularly under heavy braking or when the vehicle is lightly loaded.

Key Features:
Genuine-style replacement for original Volvo part

Mounts to the rear axle bracket

Connects between the rigid brake line and the flexible brake hose

Designed specifically for non-ABS braking systems

Essential for maintaining safe brake balance on RWD Volvo models

Compatibility:
Fits the following non-ABS Volvo models:

Volvo 240 / 244 / 245 / 265 – Model years 1975 through 1993

Technical Notes:
Front brakes on Volvo 240s use 4-piston calipers, while the rear uses 2-piston calipers.

This proportioning valve is necessary to prevent excessive rear braking force, ensuring safer stopping and improved control.

Each car uses one valve per side at the rear axle.

If your rear brakes are locking prematurely or you’re doing a full brake system restoration, replacing these valves is highly recommended.
