Re: Brakes pull to left- Brake fluids

Hi
There seems to be confusion about brake fluid specs
Brake fluid is Not corrosive ,Brake fluid will strip paint!! Brake systems corrode when the fluid is contaminated with water .
Brake fluids are Hygroscopic , they all absorb water . The water contamination both lowers the boiling point of the fluid and corrodes the metallic parts of the brake system
There is no such thing as a non synthetic brake fluid , They are all " synthetic "
Ethylene glycol is not used as a brake fluid ; It is the raw material for the manufacture[ " synthesis "] of glycol based brake fluids
There a two distinct types of brake fluids .
Glycol based
DOT 3, Dot 4 and DOT 5.1 . The main difference is their respective boiling points .DOT 4 has been the standard fluid used in the USA since 2006
DOT 5.1 is a glycol based fluid with the same high temperature properties as silicone based DOT 5
Silicone brake fluid
DOT 5 This is a completly different silicone based fluid which should not be mixed with any other specification.
DOT 5 was designed for military equipment which could be left in storage for years and is expected to be able used immediately with no maintenance
DOT 5 has the highest boiling point and is used in high performance cars ,
.Many OEM component manufacturers and car companies, including Rolls Royce, do not recommend the that Dot 5 fluids are substituted for glycol based DOT spec fluids in their braking systems.
Recommended practice if you wish to use DOT 5 in a Braking system which has previously used Dot 3, 4 or 5.1 is:
Strip and thoroughly clean the fluid reservoirs , master cylinder and brake cylinders, replace ALL rubber components in the complete braking system with DOT 5 compatible materials , flush the complete system with DOT 5 silicone fluid and bleed the system before use
Routine maintenance
It is a good idea to completly flush a glycol based system and replace the fluid every two years , even if you only do a very low mileage
I hope this helps
