SC30 Midland Haldex Brake Service Chamber T30

SC30 is a genuine Midland Haldex Type 30 brake service chamber with a standard 2.50 in. stroke, sold by Pro Gear and Transmission. The steel pressure housing is powder coated with resistance-welded air ports, and the service housing is flat-bottomed 10 gauge steel. An Orange Alert stroke indicator and a self-piloting dust shield are built in. Air pressure builds on the flexible diaphragm and drives the pushrod against the slack adjuster, so a leaking diaphragm weakens braking. Call us to confirm proper fit for your application.

A factory handling fee of $25.00 per order is added at checkout.
