Trailer Brake Repair & Adjustment Jerome, Idaho

Trailer brake repair in Jerome, Idaho is one of the most common jobs in our bays, and one of the most skipped jobs on the road. Drivers feel the tractor brakes every day. The trailer brakes only get noticed when something drags, smokes, or fails an inspection. We fix air brakes on dry vans, flatbeds, cattle pots, and tankers.

What does trailer brake repair include?

We work on the full air brake system on your trailer: brake shoes and drums, brake chambers, S-cams and bushings, slack adjusters, air lines, and valves. If your truck won't build air or you're losing pressure when you hook up, the leak is often on the trailer side — a chamber, a gladhand seal, or a cracked line.

We measure pushrod stroke and lining at every wheel, not just the one that made noise. A trailer with one bad brake usually has a second one close behind. You'll know the condition of all of them before you leave.

How long does trailer brake work take?

A brake adjustment or a single chamber swap is often same-day, and many small jobs are done while you wait. Shoes and drums on multiple axles take longer, and it depends on parts. We're open 7 AM to 10 PM every day, so there's usually a slot that works around your loads. Call (208) 696-9888 before you head in and we'll tell you what to expect.

What will it cost?

We look at the trailer, then quote the job before we start. The price we quote is the price you pay. If we find more wear than expected once the drums are off, we call you before doing anything extra. No padded bills, no mystery line items.

Why trailer brakes matter on I-84

The I-84 corridor through the Magic Valley runs heavy with ag loads — hay, grain, milk, and produce in season. Loaded trailers on black ice in January are no place to find out a slack adjuster was out of range. Brakes are also a top item at roadside inspections, and an out-of-service order costs you far more than the repair would have.

Driver questions

My trailer brakes are dragging. Can you come to me?

Yes. A dragging brake or a chamber problem is a common mobile call. We cover any I-84 exit from Bliss to Declo and state a flat call-out fee before we roll. If the trailer can move safely, shop repair is often quicker and cheaper.

My truck won't build air when I hook to the trailer. Is that the trailer?

Often, yes. If the tractor builds air fine bobtail but loses it hooked up, the leak is usually on the trailer — a chamber, a line, or a gladhand seal. We can chase it down and fix it the same visit.

Will my brakes pass a DOT inspection after you're done?

We repair and adjust brakes to meet inspection standards, and we check stroke and lining at every wheel. If you want it official, we can do the trailer's annual inspection in the same visit — our inspectors are qualified per FMCSA 49 CFR 396.19.
