Brake repairers adjust brakes, replace brake linings and pads, repair hydraulic cylinders, turn disks and drums, and make other repairs on brake systems. Some mechanics specialize in both brake and front-end work. Automotive-radiator mechanics clean radiators with caustic solutions, locate and solder leaks, and install new radiator cores or complete replacement radiators. They also may repair heaters and air-conditioners, and solder leaks in gasoline tanks. Generally, automotive and motorcycle mechanics work indoors.
Most repair shops are well ventilated and lighted, but some are drafty and noisy.
Mechanics frequently work with dirty and greasy parts, and in awkward positions, they often must lift heavy parts and tools. Minor cuts, burns, and bruises are common, but serious accidents may be avoided when the shop is kept clean and orderly and safety practices are observed. Employment Automotive and motorcycle mechanics held about 716,000 jobs in 1990. The majority worked for automotive dealers, independent automotive repair shops, and gasoline service stations. Others were employed at automotive service facilities at department, automotive, and home supply stores, or maintained the automobile fleets of taxicab and automobile leasing companies, Federal, State and local governments, and other organizations.
