GM Proportioning and Combination Valves, AC Delco 172-1353 and 172-1361 Type Chromed 19296

These GM combination-proportioning valves are based on the popular AC DELCO 172-1353(disc-drum) and 172-1361(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. 

Available in 2 and 4 wheel disc applications. Please specify.
