ITEQ Brake Fluid Liquid Tester Pen with 5 LED Indicators, Calibrated For DOT3 DOT4 Brake Fluid

Product Information

In the short term, the brakes work perfectly okay. However, brake fluid is said to be hygroscopic. This means that it has a high ability to absorb moisture from the atmosphere, and thus it should remain airtight all the time.

Usually, manufacturers have a specified mileage or period, after which you need to change the brake fluid. For the test, you would need a dirty cloth, a pentester, or a multimeter and the knowledge on how to test brake fluid with a multimeter or an LED pen. An example of a manufacturer’s plate can be found in Section 2 of the Introduction. Calculating brake efficiency A brake pedal without a rubber usually has grooves or raised sections to provide grip in wet conditions and should be rejected if it’s worn smooth. However, some vehicles may have been manufactured with a brake pedal which did not incorporate grooves or the fitting of an anti-slip material and these should not be rejected.Before carrying out a decelerometer test on the public highway, testers must ensure they are suitably qualified to drive the vehicle and are familiar with the controls. If a vehicle has special controls, such as in disability vehicles, the vehicle presenter should be allowed to drive during the test if he/she wishes. Calculating brake imbalance the actual design gross weight (DGW) where the presented weight is at least 2,000kg (the DGW is obtained from the manufacturer’s plate fitted to the vehicle)

Brake fluid is essential for ensuring your brakes work as they should. It transmits the force applied when your foot pushes the brake pedal to the brake calipers or wheel cylinders, which then applies the brakes and slows down or stops the vehicle. Brake fluid also lubricates the hydraulic system and helps prevent corrosion, so it’s important to keep it sufficiently topped up. The brake fluid chosen to put into the hydraulic system is critical, with VMs recommending a specific type of fluid that should always be adhered to. Additional braking devices, such as electronic retarders, should not be operated during the brake test. Open the bonnet find the brake fluid reservoir. If you’re unsure where this is, refer to your vehicle manual. Enter the efficiencies recorded by the meter. The MOT testing service will automatically pass or fail the vehicle on brake efficiency.De Laser kookpunttester voor remvloeistof voert een kooktest uit op een monster van de vloeistof uit het voertuigsysteem en geeft een duidelijke indicatie van de kooktemperatuur en een duidelijke indicatie of de vloeistof bruikbaar is. If the vehicle or system cannot be tested on a roller brake tester, set up the decelerometer in the vehicle as instructed by the equipment manufacturer. When testing transmission parking brakes, the minimum parking brake efficiency requirement must be calculated before the brake is tested. As soon as the minimum efficiency requirement is reached the brake testing must cease to avoid any possible damage.

Some brake fluid testers have better features than others that enable ease of use and more accurate results. For instance, one may have LED lights to show the corresponding percentage of water, while others show the percentage on a screen. One LED fluid tester pen may come with a free battery, while in others, you have to buy it separately. 4. Price The primary brake tester must be used unless the vehicle is unsuitable due to its drive configuration, transmission type or braking system. If this is the case, a decelerometer or gradient test may be appropriate. A gradient test must only be carried out if the parking brake cannot be tested using the primary brake tester or decelerometer. This will usually only be necessary on certain all-wheel drive vehicles with electronic parking brakes where no vehicle technical information is available.Often a vehicle is fitted with an aftermarket brake pedal rubber. It is not a defect if the design pattern of the brake pedal rubber is worn smooth.

You must inspect the warning lamp operation on vehicles with an electronically controlled braking system. Defect On each axle which has a secondary brake fitted, run the rollers and gradually apply the secondary brake keeping any “hold-on” button or trigger disengaged the whole time, watching how the braking effort for each wheel increases. At first glance, there’s little difference between Sealey’s VS0274 and our test-winning Laser. In fact, they were equally accurate. Research conducted for Cosan Lubricants’ Comma brand, testing the quality of brake fluid at service garages across Europe, has found that 26.5% of UK motorists had defective brake fluid, with nearly one in 10 unintentionally risking their lives every time they drove. Overall across Europe, that figure rose to 41% of vehicles operating with sub-standard brake fluid. As soon as the wheels are on the plate’s high friction braking surfaces, gradually apply the parking brake, keeping any “hold-on” button or trigger disengaged the whole time, until maximum effort is achieved.Use only the brake fluid with the DOT specification recommended in your owner's manual. There are three main specifications: DOT 3, DOT 4 and DOT 5, each having its own properties. It is possible to use DOT 4 brake fluid in some cars that call for DOT 3 fluid, but never the reverse, and DOT 5 brake fluid can be used only in cars that call for that specification. Note that most cars indicate the required brake fluid DOT at the reservoir cap. As most vehicle manufacturers recommend that brake fluid is changed every two years, the Laser Tools Brake Fluid Boiling Point Tester is an easy to use but very accurate method of testing brake fluid efficiency. You can then offer your customer accurate information with a very clear recommendation on how to proceed in this safety critical area of vehicle maintenance. Translucent plastic shows the workings inside and you need to slide the circuit board out to insert the supplied AAA battery. Yet for a clear and straightforward indication of whether your brake fluid needs replacing, the bright red, amber and green LEDs are perfect. When testing ABS equipped vehicles, the road wheels that are lifted off the ground should not be allowed to rotate when the ignition is on. This can cause the ABS system to indicate a fault which may require specialist equipment to rectify.
