BACK ORDER MASTER CYLINDER BRAKE BOOSTER SEAL
Hey guys part number 46185-sd4-932 in ontario is on backorder til late july. The master cylinder where it meets the brake booster there is a vaccum leak with a hissing noise. My rpms on cold start are about 2000rpm and engine will surge after wards sometimes. Already bleed coolant system, cleaned IAC valve. But i just realized that hissing sound and traced it back to the brake booster. in conclusion what do you guys recommend to use where the vaccum leak is. Should I use a silicone gasket maker of some sort, or is there another application someone can think of.
