Brake Controller Installation in Ringwood
Professional installation and diagnosis of electric trailer brake controllers for towing vehicles.
Workshop-based diagnosis in Ringwood for customers across Melbourne's eastern and outer-eastern suburbs.

Brake controller installation and fault-finding needs
- New brake controller required
- Trailer brakes are weak or inconsistent
- Controller displays a fault
- Brakes lock unexpectedly
- No trailer brake output
- Existing installation is untidy or unreliable
- Vehicle requires towing wiring upgrades
- Trailer recognition is intermittent
- Controller needs to suit a new trailer or caravan
Install the controller correctly and test the full towing circuit
A brake controller relies on suitable power, earth, trigger and brake-output circuits as well as a sound connection to the trailer. A controller alone cannot compensate for poor wiring or trailer-side brake faults.
We consider the towing combination, inspect the vehicle installation and test the relevant circuits. New installations use appropriately protected wiring and practical mounting suited to the vehicle and controller.
Installation and diagnosis are workshop-based in Ringwood. Vehicle compatibility, controller requirements and trailer condition must be confirmed before outcomes or timing can be known.

Frequently asked questions
Which brake controller is best for my vehicle?
The Redarc Towpro Elite is a popular choice, but it can depend on the vehicle, trailer brakes, towing use and compatibility requirements. Contact us with both vehicle and trailer details so we can discuss suitable options.
Do electric trailer brakes need a controller?
Electric trailer brakes require a compatible means of controlling brake output. Legal and towing requirements depend on the trailer and jurisdiction, so confirm the requirements for your combination.
Can you install a controller I already own?
Potentially, provided it is suitable, complete and compatible with the vehicle and trailer. We need to inspect the equipment and installation requirements first.
Why does the controller show no trailer or flash red led?
Possible causes include plug or socket faults, poor earths, damaged brake-output wiring, trailer brake issues or controller setup. Both sides of the connection may require testing.
Can you diagnose weak trailer brakes?
We can test vehicle-side controller output and accessible wiring. Trailer mechanical brake condition may require a trailer brake specialist.
How should a brake controller be adjusted?
Adjustment depends on trailer load, brake condition and controller design. Follow the controller instructions and set it so braking is balanced without locking.
Do you install controllers for caravans and trailers?
Yes, for suitable towing vehicles and compatible electric-brake systems. Provide the tow vehicle and trailer or caravan details before booking.
