Proportioning and Combination Valve, AC Delco Type 172-1353 & 172-1361, CHROME
Details
These chrome GM combination-proportioning valves are based on the popular AC DELCO 172-1353 (PV2C disc-drum) and 172-1361 (PV4C disc-disc) valves. When upgrading your vehicle from drum to disc, these small items are a must. These components ensure proper fluid transfer and contain a residual pressure valve for proper braking feel.
All valves contain a low pressure shut off valve and warning light switch to ensure driver and vehicle safety should your brake system lose hydraulic line pressure. Aftermarket imported master cylinders with built in adjustable proportioning valves DO NOT feature this and could put you and your vehicle at risk.
Applications:
- 2 wheel disc - PV2C
- 4 wheel disc - PV4C
Safety Features: This valve is designed to isolate the front brakes from the rear brakes. In the event of a failure, the emergency shut off valve detects a change in pressure and closes that portion of the brakes.
