Truck Brakes Repair Services in San Diego, California

Diesel mechanic performing brake repair services on semi truck in San Diego, CA

How Air Brakes Work

Air brakes work by converting air pressure into mechanical force to apply the brakes. A typical air brake system consists of a compressor, air storage tanks, brake chambers, slack adjusters, valves, and brake shoes. When the driver presses the brake pedal, the air pressure is released, and the brake shoes apply pressure to the drums or rotors to stop the vehicle. At Quality Mobile Fleet Services, we specialize in air brake repair and work on components such as shoes, kits, cams, slack adjusters, valves, compressors, brake chambers, and drums.

How Hydraulic Brakes Work

Hydraulic brakes work by using fluid pressure to apply the brakes. A typical hydraulic brake system consists of a master cylinder, brake lines, wheel cylinders, brake shoes or pads, and a brake booster. When the driver presses the brake pedal, the master cylinder applies pressure to the brake fluid, which then applies pressure to the wheel cylinders, causing the brake shoes or pads to apply pressure to the drums or rotors.

Bring your truck to us if you have problems with your hydraulic brakes! Aside from repairing wheel cylinders, master cylinders, brake lines, and shoes, we also adjust brake boosters.

What Our Customers
Are Saying About Us

We had a truck lose power at a receiver, and called them for assistance with a jump start. The mechanic was there in less than an hour and got our truck started and back on the road. Quick and efficient, would use them again.

Had excellent experiences with Dave and Jan at QMFS San Diego.  These folks care about their customers and back up their promises with solid mechanics that got one of my drivers back on the road and we have used them ever since when in the San Diego area weekly.

Jan and her lead mechanic were excellent.  They got our Volvo in the shop promptly and got it diagnosed and repair faster and less expensive than the other shops we were quoted.  I fully recommend their commitment to helping companies and people that are in need . Eric Z
