Jeep Grand Cherokee Brake Disc

Important Maintenance Tips for Jeep Grand Cherokee Brake Disc

The disc brakes of the Jeep Grand Cherokee require care and maintenance on a regular basis, for without it they will wear out quickly and break down when you least expect it. So if you want your Jeep Grand Cherokee brake disc to last longer, here are some tips you need to consider:

  • Keep the brake fluid at optimum levels.

The disc brake system relies on hydraulics in the form of brake fluid in order to work, so make sure to refill the brake fluid once it goes down the recommended levels. We also recommend replacing the brake fluid in the system once every two years or 50,000 miles, whichever comes first, as brake fluid tends to absorb contaminants over time.

  • Consider switching to a ceramic brake pad.

While they are typically more expensive than standard metallic or NAO pads, ceramic brake pads tend to last longer and are gentler on the disc surface. The pad's ceramic fibers also produce less dust and noise, making them less of a hassle to deal with. So while you might have to shell out more for a ceramic pad, it will be of more value for its worth in the long run.

  • Replace worn out pads.

The brake pads are designed to be expendable, and once they wear out they will not be able to bite on the brake disc properly. And while the service life of a brake pad depends on various factors, including the materials it is made of and its operating conditions, most pads today feature wear indicators that can create a loud scratching noise once the pads are about to wear out. So once you hear abnormal noises from your disc brakes, it may be time to retire the pads and replace them with new ones.

  • Turn or replace?

Brake discs that have a scored, pitted, other otherwise damaged surfaces will not be able to engage the brake pads properly, but if the damage is minor it might be still be fixed by "turning" the rotors. "Turning" is basically shaving off a small layer of the brake disc surface in order to remove the damage, but it comes at the cost of thinning the disc and making it more vulnerable to warping. So while having the disc turned might be a cheaper option, it will also make it more vulnerable to damage in the future. In addition, it is also not recommended to "turn" discs that have already been machined or warped, as these must be replaced instead.

  • Tips on Replacing the Jeep Grand Cherokee Brake Disc

    Replacing a Jeep Grand Cherokee brake disc can be an exhaustive and messy task, but it's a necessary one if you want to your vehicle to have functional brakes. Along with the brake caliper and brake pads, the brake disc or brake rotor is one of the three key components of the modern disc brake system. And if it is broken or defective, a failing brake disc can result in reduced or zero braking functions in your car.

    If you are planning on installing a new brake disc on your Jeep Grand Cherokee, here are some tips to keep in mind:

    Tip #1: Loosen the wheels' lug nuts before raising the vehicle.

    Though not essential, loosening but not removing the wheels before lifting your car will make it easier for you to remove it later on. This is because the wheels are held in place by the ground, whereas if it is lifted in the air there will be less resistance when you turn the wrench.

    Tip #2: When removing the brake caliper, don't let it dangle freely from the brake hose.

    The brake hose is quite fragile and will tear easily from the weight of the brake caliper, rendering it unusable. To keep the brake calipers safely out of the way, you can either use a piece of string and tie the caliper on a secure part of the undercarriage or lay the caliper on an elevated stable surface such as box or a crate. We also recommend laying an oil pan or a similar receptacle under the brake caliper to catch hydraulic brake fluid bleeding out from the hose.

    Tip #3: Spray the new rotor with brake cleaner.

    Applying several coats of brake cleaner on your new set of brake discs will help it repel dust, grime, and moisture from the disc surface. Brake cleaning products are readily available in most auto parts and hardware stores.

    Tip #4: Check the brake fluid levels and replenish if necessary.

    Replacing the brake caliper will inevitably cause some of the brake fluid to leak out of the brake lines, and if too much drains out there may not be enough hydraulic pressure for the brake pads to engage the disc surface effectively. So once the new brake calipers are in place, check the brake fluid gauge; if the fluid is below the recommended levels, refill it accordingly.
