Brake Service in Portland, OR

Brakes fail inspections more than anything else

Brakes are the number one DOT violation category nationwide. Out-of-adjustment brakes, thin linings, air leaks, inoperative ABS. Your fleet runs Portland routes every day. Hills, stop-and-go traffic, wet roads. The braking system takes a beating that flat-terrain fleets never see.

Three of your trucks need brake work. The shop on Columbia Boulevard says bring them in. One per day, three days of trucks off route. Or you put it off and hope they pass the next DOT inspection. They will not.

We come to your yard. All three trucks. Same visit. Brakes measured, adjusted, parts replaced. All three trucks documented to FMCSA standards. All three rolling on their routes the next morning.

Portland hills eat brakes

Portland is not flat. West Hills deliveries, Sylvan area access, the Terwilliger grades, Rocky Butte. Trucks running these routes use their brakes harder than trucks on flat I-5 corridors. Add the constant rain and wet roads, and braking distances increase while pad wear accelerates.

If your fleet serves the hilly parts of Portland, brake inspections need to happen more often than the minimum intervals suggest. We build brake check schedules around your actual routes and driving conditions.

What brake service covers

Brake pad and shoe replacement. Drum and rotor inspection, resurfacing, or replacement. Slack adjuster inspection and replacement on air brake systems. S-cam and bushing service. Air brake chamber replacement. Air line repair and system leak testing. ABS sensor replacement and module diagnostics. Brake valve service. Parking brake adjustment. Complete brake measurement documentation for DOT records.

Air brake system work

Commercial air brake systems have more components than people realize. The compressor, air dryer, governor, tanks, supply lines, service lines, relay valves, quick-release valves, slack adjusters, S-cams, brake shoes, drums, and chambers. A problem in any one of these components affects the whole system.

We test systematically. Compressor output, governor settings, air dryer function, tank drain valves, all supply and service lines, every brake chamber. An air leak that drains your system overnight might be a tiny crack in a nylon air line that takes 30 seconds to replace but two hours to find.

DOT brake compliance

At the Woodburn scales south of Portland, DOT officers measure brake adjustment and lining thickness. If your numbers are off, the truck goes out of service. No exceptions, no warnings. The driver sits until a mechanic comes and fixes it.

We measure brakes to the same standards DOT uses. When we sign off on a brake job, those numbers hold at the scales.

Emergency brake repair

A brake line rupture on I-5 is an emergency. A wheel lockup on a loaded trailer is an emergency. A complete loss of air pressure is an emergency. We dispatch for brake emergencies immediately. Highway shoulders, parking lots, wherever the truck stopped safely.

Trailer brake service

Trailer brakes are out of sight and out of mind until they fail an inspection or a wheel locks up. We service trailer brakes with the same thoroughness as tractor brakes. Shoes, drums, chambers, air lines, ABS sensors, and glad hand connections.
