What type of brake fluid should I use with Wilwood brakes?
Wilwood’s specially formulated Hi-Temp° 570 Racing Brake Fluid has a minimum 570° F. dry boiling point of to withstand the severe heat requirements of automotive racing.
What is silicone brake fluid?
A silicone brake fluid is also known as a DOT 5 brake fluid. Silicone brake fluids are not hygroscopic so they do not absorb moisture. They are extremely expensive. compared to standard polyglycol based fluids, and may require compatible braking system components before these can be used.
Should I use DOT3 or 4?
The primary differences between the two include the following: 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 is DOT 4 brake fluid for?
Mobil Brake Fluid DOT 4 is an extra high performance hydraulic brake fluid for use in automotive disc, drum and anti-skid brake systems and clutch systems.
Is DOT 5.1 better than DOT 4?
As DOT 5.1 is more hygroscopic than DOT 4 and therefore absorbs more moisture, it will need to be changed more often. However, the benefit of 5.1 with its higher boiling point, is that it can experience higher temperatures than DOT 4 before it starts to affect braking efficiency.
How can you tell the difference between DOT 4 and DOT 5?
While both fluids are glycol ether based, DOT4 contains a certain amount of borate ester which allows it to handle more heat. DOT5 is a silicone-based fluid that was developed for use where moisture or water was almost certain to be a factor in the braking system, such as military applications.
Is synthetic brake fluid better?
Some very high-end synthetic DOT 4 and 5.1 synthetic fluids can give a better pedal. But, it is so small of a difference that only the very, very, very best drivers can feel it. Some silicone-based fluids can provide a softer pedal because it is more compressible than glycol-based fluids.
Is it OK to mix brake fluids?
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. By mixing DOT 3, 4 and 5.1 brake fluids, assuming it is fresh fluid, the worst thing that can happen is a drop in the boiling point of the whole fluid.
What’s the boiling point of Wilwood racing brake fluid?
EXP has been proven to maintain firm pedal feel and quick response, long after others have failed. Wilwood’s specially formulated Hi-Temp° 570 Racing Brake Fluid has a minimum 570° F. dry boiling point of to withstand the severe heat requirements of automotive racing.
How big is the stroke on a Wilwood disc brake?
Wilwood’s TM1 Master Cylinder features a.625” bore and 1.3” stroke, and fluid inlets specifically designed for remote reservoirs.
What kind of master cylinder does Wilwood use?
Wilwood’s clutch slave cylinder is a “Pull Type” made from billet aluminum and features a stroke of 1.375”, plenty long enough to assure full release of the clutch. Wilwood’s Handlebar Master Cylinder is used on several small vehicles by many manufacturers, and it’s now available to you.
Is it OK to use DOT 5 brake fluid?
Wilwood does not recommend using DOT 5 fluid in any racing applications. Wilwood’s new XR Race-Only* brake fluid is the same extreme high-temperature fluid used in Formula 1, World Rally Championship, FIA World Endurance, and Moto GP.
