Replacement frequency
Brake design, especially disc brakes (hollow pistons that give off little heat, a small volume of brake fluid inside the cylinder, floating brake calipers, which made it possible to do without a brake fluid reservoir in the least cooled area of the wheel), made it possible to practically eliminate the risk of vapor locks forming even with intensive use of the brakes, for example, in mountain conditions.
During the first few months of operation, the properties of modern brake fluids still deteriorate slightly due to low moisture absorption and therefore it is recommended to replace the brake fluid.
Topping up brake fluid
As the brake pad linings wear, the level of brake fluid in the reservoir gradually decreases, which, however, does not need to be compensated for, since the level will rise again after replacing the brake pads. At the same time. it must not be allowed to fall below the minimum acceptable level
Approved brake fluids
Mixing two incompatible brake fluids in a hydraulic actuator can result in significant fluid leaks, primarily due to deformation of the seals and O-rings. To prevent this, you must only use brake fluids that have been tested and approved by the technical department and that meet the SAE J 1703 DOT 4 standard.
