The brakes of a car can overheat for many reasons. Especially in hydraulic systems one of the most common problems, and one of the easiest to solve, is the incorrect placement of the brake pads on the brake disk. Ferodo offers several basic guidelines for the problems between the brake pads and brake discs and the procedure for their most accurate positioning.
The distance between the pads and discs may be too large or too small. Depending on this, different problems arise:
- In case of large clearance there is a risk that the brakes will be damaged because the brake pads do not rest on the discs and do not achieve good friction. This can significantly weaken the brakes and lead to dangerous situations.
- If the gap is too small, the brake pads and discs can touch without pressing the brake pedal, resulting in undesired friction, wear and overheating of the components, which can again impair the performance of the brakes, cause vibrations, noise and permanent damage on the discs. In the worst case, hot spots are formed that can quickly wear the material and crack the discs.
The optimal positioning of the brake pads on brake discs helps to prevent overheating. Ferodo recommends regularly checking the gap between the two components - as a rule, if they are not added, the linings are gradually spaced because they wear out and become thinner. All hydraulic disc brakes are fitted with a self-adjusting self-tapping drive when braking to compensate for disc and pad wear. However, they must be checked regularly to ensure that the performance of the braking system is optimal.
If the controller is installed properly, automated setup should not require additional manual intervention. However, the position must be checked regularly by a fitter - for example, when replacing the linings or if there is overheating. If it is found that the automatic regulator passes the permissible maximum, this is usually a sign of other system problems that need to be checked.
Safety in 9 steps:
- Remove the brakes and secure the vehicle so that it can not move.
- Remove the tire.
- Install the brake assembly to the guide pins. Remove the outer lining from the plunger and check both the inner lining of the lining and the lining.
- Check the gap between the plunger and the inner lining with the help of a chuck plate. It must be in the range recommended by the manufacturer.
- If the distance is less than or greater than recommended, continue with steps 6 through 9 of the procedure.
- Manually adjust the distance as specified by the manufacturer.
- Push the brake 50 times.
- Recheck the clearance with the gauge plates to make sure it is still within the range recommended by the manufacturer.
- If the clearance is still less than or greater than recommended, the entire structure or parts of the structure must be replaced according to the manufacturer's instructions.
