A heavy semi-trailer at dusk, the kind of rig B&R Mechanical Services keeps braking safely

Heavy trailer brakes,
diagnosed and fixed properly.

B&R Mechanical Services is a husband and wife team in Adelaide specialising in ABS, EBS and trailer braking systems. Mobile across the metro, or in the workshop.

We read Haldex, Wabco and Knorr-Bremse systems for operators around Adelaide and regional South Australia.

When a trailer throws a brake fault, you do not need a guess and a new part on the invoice. You need someone who reads EBS like a second language, finds the actual fault and gets the rig back on the road. That is the whole job here.

What we do

Trailer braking is all we point at, so it gets done right the first time. Diagnostics, repairs, upgrades and the servicing that keeps faults from stranding you.

  1. 01

    ABS & EBS fault diagnostics

    We plug in, read the codes and trace the real fault: sensors, modulators, wiring or valves. No parts-cannon, no guesswork.

  2. 02

    Trailer brake repairs & overhauls

    Air lines, brake chambers, slack adjusters, S-cams and relay valves. Stripped, checked and put back within spec.

  3. 03

    Haldex & EBS upgrades

    Gen 2 to Gen 3 conversions and module replacements, set up and tested so the whole system talks properly.

  4. 04

    Roadworthy & compliance checks

    Brakes measured and documented so the trailer stays legal and inside the numbers it needs to hit.

  5. 05

    Preventive maintenance

    Scheduled servicing on your terms so small faults get caught on the hoist, not on the side of the freeway.

  6. 06

    Mobile call-outs

    We come to the yard or the breakdown across Adelaide when the trailer cannot come to us.

On the job

Real trailers, real faults, sorted. Here is a recent one.

Southern Cross drop deck, Haldex Gen 2 to Gen 3 upgrade

A Southern Cross drop deck mezzanine came in for a full Haldex unit replacement, stepping the EBS up from Gen 2 to Gen 3. New module fitted, lines run, brakes set up and the whole system tested before it left. Another install done and back earning.

The B and the R

B&R is a husband and wife team. We started in 2025 to do one thing the way it should be done: trailer braking, properly diagnosed and properly fixed.

When you call, you talk to the people doing the work. No call centre, no service advisor reading off a screen. You get an honest read on what is actually wrong and what it takes to fix it.

  • Straight to the people on the tools
  • Honest diagnosis before any parts go on
  • Workshop or mobile, whatever suits the job
