1. 1. On a car with disc/drum brakes, the front brakes grab quickly when light pedal pressure is applied. This problem could be caused by a bad: A. proportioning valve B. pressure safety switch C. metering valve D. residual check valve: 1. The correct answer is C. The metering valve delays the flow of brake fluid to the front calipers until the pressure in the system rises to a point where the wheel cylinder can overcome the tension of the brake shoe return springs. The purpose is to have b...

R-22 vapor line diameters and lengths are typically specified for a: Vapor pressure drop that does not exceed 6 - 7 psi or 6°F. The primary purpose of using flux when soldering copper or brass parts is to: Prevent oxidation. The water that results from a defrost cycle of an air to air heat pump (runoff) must: Drain off and away from the outdoor coil to prevent excessive ice can build up on the bottom of the coil and reduce capacity. The component used to reduce sound tra...
