Isuzu NRR: Maintaining the Brakes’ Good Condition
The Isuzu NRR can do some heavy lifting on the road. To make sure that driving the NRR will be safe, you have to make sure that the brakes are in their best shape. This will give you better control when on the road. If the brakes are properly maintained, this Isuzu will stop and slow down easily even when it's loaded with some heavy cargo or it's running at highway speeds. To get the best possible braking performance from this Isuzu, regular brake checkups will help a lot. Here are some tips:
Brake squeals and grinding when you step on the brake pedal will tell you that something's amiss with the brakes, particularly the pads. Before the pads get too thin, you should be able to replace them. Some brake pads can be checked through the wheel. Through this, you can tell if they're already too thin or will need replacement. In some pads, you can confirm if they're due for replacement through a warning sensor or a wear indicator, which is a slot in the center. If the slot can be barely seen, then you should be shopping for new pads. Measure the thickness of the pads both at the top and at the bottom and see if this meets the recommended thickness level by the manufacturer. If the lining on the pads is reduced to the steel backing plate's thickness or there's little friction material left on the plate, then the pads should be replaced.
You can't tell if the brake rotors need to be replaced simply by looking at them. These require a more thorough inspection than pads. Having a thin layer of rust on the rotors isn't unusual. The surface rust doesn't affect brake performance. This can disappear when the brakes are applied, though you may still find some traces on the hub and/or vents. If rust, however, is already etched into the rotors, then this isn't okay anymore. The corrosive rust will compromise the strength and effectiveness of the rotors. As such, rotor replacement is highly recommended. The disc should be checked not just for corrosion but also for uneven wear and other common signs of rotor damage. If you find some visible cracks upon inspecting the rotors, then you should consider replacing the discs. Aside from these, you should also watch out for grooves, edge lips, and warpage. If there are heat spots, then this means that the discs suffer from uneven brake pad deposits. Heat spots can cause vibrations and brake harshness and will affect the structural integrity of the rotors. Be sure to replace the rotors even before they exceed the minimum thickness limit. You can measure the thickness of the rotors using a micrometer. If the rotors are scored, they may be resurfaced until the wear limit is reached. However, if the scores are too severe or the grooves are too deep, it would be best to replace them.
- Check the brake fluid and other brake parts.
Aside from the brake pads and rotors, also check the brake caliper. See if it's still mounted properly or if any hardware is worn out. The brake line and hose should likewise be inspected for leaks and cracks. Also don't forget about the brake fluid. Make sure that there's enough in the system. Other than the fluid level, also check its condition, if it's already contaminated or still in good quality. You can usually tell by the color, although it would also be best to use some tools for testing the brake fluid condition, such as a chemical test strip to determine the existence of copper in the fluid, an optical refractometer to test for moisture content, and an electronic tester to assess the boiling point.
