Bendix Brakes Trusted for GVM Upgrades and Heavy Towing
There are few luxuries afforded to a busy independent workshop, but perhaps the rarest of all is the opportunity to do the same job twice.
At Dr Shocks Suspension and Brakes in Brookvale on Sydney’s Northern Beaches, the hoists rarely sit idle long enough for anyone to contemplate philosophical questions about brake friction coefficients, metallurgy or the curious ability of some aftermarket components to look perfectly acceptable until the moment they are asked to do actual work.
Father and son team David and Josh Mastroianni operate the three-hoist workshop with the quiet efficiency that only comes from years spent diagnosing mechanical problems under time pressure and customer expectation.

Workload
Because when your daily workload might include anything from a routine service on a Volkswagen Tiguan to a brake job on a well-travelled Holden Rodeo, followed immediately by a GVM upgrade on a heavily accessorised Toyota LandCruiser 200 Series, the margin for experimentation with unknown parts tends to narrow rather quickly.
And in a small family business, a comeback is not merely an inconvenience. It is an interruption to workflow, a disruption to customer confidence, and most critically, time that cannot be invoiced.
David understands this reality well, having spent 20 years working within dealership environments before purchasing the Brookvale workshop in 2010. Since taking ownership of Dr Shocks, Bendix braking components have become something of a constant presence in the workshop.
“Bendix has been in the game for a very long time and they really know what they’re doing,” David explained. “We’ve never had any issues or comebacks with the Bendix range. Everything fits perfectly, unlike some other brake brands we’ve come across.”
Fitment accuracy may not sound like an exciting topic for casual conversation, but in workshop terms it represents the difference between a straightforward installation and the sort of extended parts interpretation exercise that can quietly erode both profitability and patience.
Practical Features
More recently, the workshop has begun fitting Bendix’s General CT™ Disc Brake Rotors, designed to pair with General CT™ Brake Pads. Among the more practical features is the visual wear indicator, allowing technicians to quickly assess rotor thickness at a glance without reaching for measuring tools.
In an environment where workflow efficiency is measured in minutes rather than marketing claims, small details like this can add up to meaningful time savings over the course of a full service schedule.
“The wear indicator is definitely a feature that will save us some time in the future when customer cars return for a service,” David said.
Suspension upgrades and GVM increases form a substantial portion of Dr Shocks’ workload, particularly given the steady growth in Australians towing caravans, boats and trailers across increasingly ambitious distances.
With increased mass comes increased braking demand, and David said recommending Bendix Ultimate 4WD™ Brake Upgrade Kits alongside GVM upgrades has become common practice.
GVM Upgrade
“Customers going for a GVM upgrade are obviously interested in carrying and towing more, so upgrading the brakes at the same time makes a lot of sense,” he explained. “About half of them choose to upgrade the brakes straight away, and then we get others who come back for a check a few weeks later, have thought about it more, and then decide to go ahead.”
As David tells it, some customers require more persuasion than others, although occasionally the laws of thermodynamics intervene on behalf of the service advisor. “I had one customer who came back for a routine check after a GVM upgrade we’d recently done, and he rolled in with his brakes smoking. He needed no convincing after that.”
Real-world durability is where brake components ultimately earn their reputation, and feedback from customers returning from long-distance towing and remote touring has been consistently positive.
“We had one customer come back after doing 20,000 kilometres of heavy towing and when we inspected the rotors, there wasn’t a scratch or groove on them,” David said. “It was a similar story with another customer who did a trip to the Cape. On a previous trip he had another brand of brakes and came back with cracked rotors after hot brakes went through river crossings. This time, with the Bendix components, there were no issues at all.”
Deliver Solutions
In an era where vehicle weights continue to increase and expectations of performance rise with them, workshops are increasingly expected to deliver solutions that perform consistently across a wide range of conditions.
For Dr Shocks Suspension and Brakes, component choice is less about brand loyalty and more about risk management. Because in a workshop where every hoist is booked and every job matters, the ideal brake component is not necessarily the most exotic or heavily advertised. It is simply the one that fits properly, performs predictably, and does not come back. And in a busy family workshop, that might just be the most valuable feature of all.
