We have the most important information on this topic. Yes, first a few details on how vehicle brakes work. With the Depressing the brake pedal hydraulic pressure is generated in the master brake cylinder, which is brake fluid in the brake lines to the wheel brakes. Corrosion on the rigid brake lines is one of the main reasons for Leaks. The brake line is restricted due to the loss of brake fluid. In the worst case, this can lead to the braking system fails completely. If you have any suspicion, you should go to a workshop as soon as possible. If the braking effect is already limited, the car should no longer driven, rather towed away .

Repair or just a new line?

In a first step, it is determined wo where the leak is. The affected line section must then be replaced. First the brake fluid drained, to then close the affected line dismantle. The effort required for this is very individual, as it depends on which place is affected and of course also by the type of vehicle. This can occasionally lead to a great deal of effort if the position is difficult to access. In this case it may even be that just removing the underbody paneling is not enough. Depending on the construction, it may then be necessary to remove the rear axle or even the tank. For the new part, either a "ready bent" vehicle-specific line or meter in question. The preparation for the second option is quite complex, since the new part has the same shape as the old one and accordingly must be bent. If the line is bent, or the vehicle-specific one has arrived, then it can be installed after the new piece with Hollow/socket screws was fitted and at the connection points crimped would. Then will new brake fluid filled into the system and this with a special brake bleeding device vented. After that there will be another test drive carried out to test the effectiveness of the system.

The price of changing a leaking pipe!

The material costs for a new brake line can vary quite a bit and depend on the vehicle and the damage that has occurred. The brake line can either be made individually by hand (bent / beaded) or replaced by a "pre-bent" one. It is not possible to say in general which variant is the cheaper one. The workshop decides this depending on the case at hand. Self-manufactured brake lines offer the advantage that you don't have to wait for the spare part first, but for the vehicle rinse can be repaired and is therefore available again more quickly. The material costs are usually between 10 and 100 euros.

Leaking brake lines for the main inspection!

Leaks in the brake line are always noticed during the general inspection, since the brake system does not meet the prescribed values ​​on the brake test bench can not reach. This is a significant security risk and the main inspection is therefore considered failed.

the importance of the braking system

Hydraulic pressure is transferred from the brake pedal to the wheel brakes using brake fluid. The brake lines extend from Master Cylinder with reservoir in combination with the ABS/ASR module in the engine compartment along the underbody to each individual wheel. There are both rigid and flexible brake lines. The flexible lines are mainly used between the rigid brake pipe and the wheel brake. In the course of repairs, and if money plays a secondary role, it is advisable to jump to more robust Steel braided line - brake line to convert
