Also silicone fluid absorbs air instead of water so it's important to bleed it thoroughly and just as important to keep it covered. Too much air absorbed can cause a spongy feel in the brakes.

DOT5 stops rust because it will not harbor water. DOT3 is a paint remover, DOT5 Silicone is not. So it's worthwhile to use DOT5 Silicone. Every 55-56 Plymouth I ever saw has paint missing under and around the master cylinder from brake fluid filling spalsh. The reason you flush out the non DOT-5 is to get the water out. Since DOT5 silicone will not absorb water, the water can pool in the lines and cylinders. ----- Original Message ----- From: "Joseph Bouboulis" <Joseph_Bouboulis@xxxxxxxxxxxxx> To: <L-FORWARDLOOK@xxxxxxxxxxxxx> Sent: Tuesday, May 01, 2001 2:26 PM Subject: Re: [FWDLK] brake bleeding sequence? > You bleed from farthest to closest. > > The main difference between the different dot levels of brake fluid is > resistance to temperature.
