UTSAUTO Brake Proportioning Valve - Disc/Disc System With Bleeder Tool

About This Product

Classic car and truck enthusiasts working on brake upgrades, this UTSAUTO proportioning valve is designed for vehicles with disc brakes front AND rear. Based on the popular AC Delco 172-1361 valve, it helps balance brake pressure between front and rear to prevent rear wheel lock-up - crucial for safe braking performance. The brass construction ensures durability, and the port sizes are specifically designed for brake systems: two 3/8-24 ports for front calipers, one 9/16-18 port for rear brakes, and master cylinder connections at 1/2-20 and 7/16-24. The kit even includes a bleeder tool (replaces AC Delco 172-1353/172-1371) for non-adjustable GM-type valves, which is super handy when you're bleeding the system after installation. Whether you're upgrading an older vehicle to four-wheel disc brakes or replacing a faulty valve, this combination valve is essential for proper brake balance. It's the kind of component that makes a noticeable difference in braking feel and safety - no more scary rear-wheel lock-up during hard stops. The quality construction matches or exceeds OEM standards, and having the right ports means no adapters or modifications needed. Your brake system will work as intended with proper pressure distribution front to rear.
