MECHANIC'S CORNER: Leaking Brake Fluid


This week an early 2000 Honda Civic came in the shop with the complaint that there was fluid that was leaking in their garage. Taking a peek under the hood, it was seen that the brake master cylinder has a leak.

master cylinder is a control device that converts non-hydraulic pressure (from a driver's foot) into hydraulic pressure.

Seeing as there is no damage to the master cylinder except for that small leak, the remedy to this problem is to fabricate a gasket to seal the leak. This was achieved by taking a rubberized material (designed for gasket use - as seen in the image at the right) and cut-out the shape that would make a snug fit to the leaking portion of the master cylinder.

Further inspection also showed that the leak was not only caused by the master cylinder but a leak was also found in one of the brake hoses. This problem is easily resolved by replacing the leaking hose with a new one.

In this modern times, it is common for mechanics to replace parts rather than repair them. However the art of repair is a skill that should not be overlooked and is still an effective and cost-efficient way of taking care of car problems today.
