Brakes

From the 1943 United Motors War-Time Service Handbook

Hydraulic brake diagnosis arranged by symptom: pedal goes to the floor, brakes drag, one wheel drags, car pulls to one side, springy or spongy pedal, excessive pedal pressure, brakes too severe and brakes squeak. Remedies include finding external leaks, bleeding air, master cylinder check valve and compensating port, flushing out mineral oil contamination, anchor pin adjustment, linings and drums.
