Re: 1970 Blazer Brake Question
BULL!
DOT 5 is a ***** to get microscopic air bubbles out of. I had a heck of a time bleeding a system on a friends 1973 Trans Am. We could not get a very good pedal feel, and eventually flushed the system, replaced all of the rubber and went with DOT4. Problem solved....

The main difference between DOT 3 and 4 is the boiling point. Dot 5 is silicone brake fluid and should NEVER be used for daily driven street vehicles, but I guess you learned the hard way and figured that out. Last edited by hemi43; 01-09-2024 at 10:16 AM. |
