Intervals for changing brake fluid
The technology of our brakes and in particular disc brakes (hollow pistons transfer little heat, little fluid in the cylinder, floating calipers, eliminating the need for a relatively large supply of hydraulic fluid in the least cooled part of the wheel), to minimize the risk of «steam locks» even in the case of frequent and prolonged use of the brakes (in the mountains). However, the performance of the brake fluid deteriorates somewhat during the first months of operation due to the slight absorption of moisture. This necessitates the replacement of the brake fluid.
Adding brake fluid
As the brake pads wear, the level of brake fluid in the reservoir gradually decreases.
There is no need to compensate for this drop, the level will be restored at the next brake pad change. At the same time, the level should not be allowed to fall below the mark of the minimum allowable level.
Approved brake fluids
Mixing two incompatible brake fluids in a hydraulic actuator can lead to significant fluid leaks, mainly due to deformation of the seals.
To prevent this, use only brake fluids that have been tested and approved by the technical department and that comply with SAE J 1703 - DOT4.
For optimal vehicle braking performance, RENAULT recommends using low viscosity brake fluids at low temperatures (no more than 750 mm / s at 40°C).
