Brake System Problems
Shortly after Project: MGB was delivered, a small puddle began forming under the left-rear wheel. Upon removal of the wheel and drum, the brake cylinder was identified as the culprit. It was rather corroded, the gaskets were shot, and only a light touch to the system resulted in the free flow of hydraulic fluid. The rear wheel cylinder was pulled and cleaned, but internal corrosion had damaged the system beyond repair, and a new one had to be purchased.
Because of the identified safety issue, review of the entire brake system was accelerated. The pedal box was rusted, the push rod and gaskets of the master cylinder were completely corroded, and the interior of the master cylinder was showing some problems. The disc brakes showed some grime, but the right rear drum back was near failing like the left. While the lines looked to be protected by almost 50 years of grease, tar, and dirt, safety must always take priority, so the decision was made to scrap the entire system.
From the original system, the irreplaceable pedal box, master cylinder mount, and handbrake assembly, and a few clips, will all be cleaned, sanded, reprinted, and reused. The rest of the brake system, including the pipes and hoses, will be replaced in keeping to the original design with all new parts. While a seemingly monumental effort that can be made more complicated without a lift or complete tear down of the vehicle, this task can be performed at home by any qualified mechanic willing to put in the time and effort.
