Is all DOT 4 brake fluid the same?
No. LHM and DOT-type brake fluids are very different. Do not mix them up. If the wrong fluid is used it can, and probably will, result in complete failure of the braking system.
What are the 3 types of brake fluid used today?
The three main types of brake fluid now available are DOT3, DOT4 and DOT5. DOT3 and DOT4 are glycol-based fluids, and DOT5 is silicon-based. The main difference is that DOT3 and DOT4 absorb water, while DOT5 doesn’t. One of the important characteristics of brake fluid is its boiling point.
Does it matter what kind of brake fluid I use?
Although DOT 3 and DOT 4 fluids are all glycol-based, the chemical composition of each type of fluid is different, so it will have a different effect on the system. To ensure that the system works as it should, it is imperative to keep using the exact brake fluid recommended by the manufacturer.
Can you mix brands of brake fluid?
Since DOT 4 and 5.1 are both glycol-based brake fluids they are compatible with each other, which means they can be readily mixed without harming your brake system. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid.
What happens if you use DOT 3 instead of DOT 4?
DOT 3 brake fluid will absorb less water than DOT 4 from the air over time, meaning you’ll need to have your fluid changed less frequently. DOT 4 brake fluid has higher dry and wet boiling points, making it safer for higher temperatures.
What type of brake fluid should I use?
The original brake fluid grade. Now mainly recommended for older vehicles. Provides a higher margin of safety. Recommended by most vehicle manufacturers. Advanced low viscosity fluid, to optimise the performance of ESP / ASR systems.
What type of brake fluid does Rolls Royce use?
A DOT 4 military grade brake fluid that conforms to OX-8 and NATO code H-542. This product has been specially formulated for use in Rolls Royce and Bentley vehicles produced prior to 1980 and fitted with a metal reservoir. A mineral-based fluid used for some older Citroëns and other vehicles and applications where specified.
What is ox 320 oil for?
(Re-mortgage the house first.) OX 320 is occasionally called up as an additive to the reduction hub oil, this is colloidal graphite in suspension and does little or nothing except make the oil very black, its prime use is gun recoil slides.
What type of fluid is used in suspension fluid?
A synthetic oil-based fluid specified for certain suspension, traction control and central locking systems.
