SC30L Midland Haldex T30 Long Stroke Service Chamber

The SC30L is a genuine Midland Haldex T30 long stroke service chamber with a 3.00 in (76 mm) available stroke. The steel pressure housing is powder coated with resistance welded air ports, and the diaphragm rubber stays flexible down to -40°F. Studs sit on 4.75 in (120.7 mm) spacing with 5/8-11 UNC threads, and the air ports are 3/8-18 NPTF. Air fed to one side of the diaphragm pushes the pushrod out, turning the slack adjuster and cam that press the shoes against the drum. A return spring draws everything back on release. A hiss at the chamber, slow brake application or pressure that bleeds down in a leak test points to a torn diaphragm. Call us to confirm proper fit for your application.

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