As brake fluid is essentially the life blood of the braking system, garages and mechanics play an important part in keeping motorists safe on the road as monitoring the fluid’s condition rarely makes most drivers’ to-do-lists.

The process of testing brake fluid is very simple, and exact boiling points can be identified easily using a brake fluid tester. Where possible, it’s recommended to perform the test in the master cylinder reservoir of the car, by inserting the probe and ensuring its end sits below the fluid level. Before performing the test, the equipment must be connected to the car battery, which is used to heat the brake fluid.

However, as with all equipment, it’s key that the device is easy to use. Because of this, Mintex has launched a new brake fluid tester, designed to help users efficiently and accurately check fluid levels. As part of Mintex’s new tools collection, the brake fluid tester is incredibly practical and features an LCD screen, which guides the user through each step of the process, making the device a popular choice for garages.

With regards to the testing process, as the car battery heats the brake fluid, the testing probe will measure the temperature, which takes an estimated 30 seconds. Once this is complete, the operator is left with an accurate temperature reading. Before and after readings can also be shown to customers, demonstrating the difference in fluid levels, and in turn, the importance of the test. A simple test using this tool can save valuable operator time, as well as increasing the garage’s profit potential.

The Mintex brake fluid tester will not only speed up throughput of routine jobs, but it also provides an opportunity for an additional brake servicing business. This could result in an average-sized workshop making an extra £14,700 annual profit each year, as seen in the brake fluid profit potential calculation*.

Alongside the brake fluid tester, the new tools range features a full suite of items, from hub grinders and pneumatic piston windback tools, to caliper cleaning files and caliper housing guide bolt sets. The tools provide the Mintex seal of quality that is well known within the industry and have been tested at the company’s specialist technical centre. Furthermore, they are backed by support from the Mintex technical team.


*Brake fluid tester profit potential calculation:

Check the profit potential
Average sized workshop daily throughput 8 vehicles
Cars tested below minimum recommended level 6 vehicles
Go ahead to change fluid 2 vehicles
40 minutes labour @ £24/hour £16.00
Minimum profit on fluid (1 litre) £3.00
Profit per vehicle £21.00
Payback period on 2 tests/day 9 days
Potential annual revenue (700 cars @ £21/vehicle) £14,700

Example shown is a rough projection, for illustration purposes only – users should estimate their potential profit return based on their actual costs and anticipated volume of customers for their business.

    Labour £16, brake fluid £3.00, how do you get a profit per vehicle of £21.00? It makes no sense!!
