Brake Fluid Dot 3 or 5.1

colin172 · 10-13-2007, 08:58 AM

My brake fluid needs topping up as it is down to the minimum level. It says in the owners book use only Dot 3 but this is no longer available according to my local Toyota garage. They now only sell Dot 5.1. Can I use this in my '89 Supra?

Yes they still sell Dot 3, go to your local Checkers or Autozone.

if your car has abs do not use dot 5. whatever is in dot 5 ruins the abs control module
