In a disc circuit, 2 PSI keeps the pads close to the rotor without dragging, so the pedal is firm and the first part of the stroke does useful work. When a residual valve sticks open you get a long or soft pedal and may need to pump it; when it sticks shut the brakes can drag and run hot. On disc conversions and on master cylinders mounted low in the chassis, a 2 PSI valve also stops fluid draining back to the reservoir. The wrong rating is a common mistake: 10 PSI belongs in a drum circuit, and fitting it to discs causes drag.\u003c\/p\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNote the flow direction before removing the old valve; install the new one the same way (outlet toward the wheels).\u003c\/li\u003e\n\u003cli\u003eUse brake-rated thread sealant on NPT threads only, never on flare seats, and keep sealant out of the bore.\u003c\/li\u003e\n\u003cli\u003eUse proper adapters when joining 1\/8\" NPT to metric bubble-flare lines.\u003c\/li\u003e\n\u003cli\u003eBleed the system fully after installation and check for leaks under firm pedal pressure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it fit my 1970 Bus?\u003c\/strong\u003e\u003cbr\u003eEMPI lists it for 1968–1972 Buses.
