Review on ACDelco 18J4621 Professional Passenger Hydraulic by Glenn Rodgers

Used on a 2012 Chevy Tahoe. This hose should be OEM/Acdelco and I believe it is. It came in an Acdelco box and has all the necessary markings. The main hose and ends are identical to the originals BUT the supplied copper washers are the wrong size and may cause the unit to leak. They are too wide, I had to reuse the old smaller/thin washer between the end of the hose and the caliper. The outside of the hose tip works well with a larger shim. Washers - the only thing that is attached in addition to the purchase. No screws or clips. The hose end fitting on the brake line side is slightly different (maybe a newer design) but works well.
