FAQs—Chrysler Brake Disc and Pad Kit
The uneven wear on the brake disc may be caused by a wide set of factors, which include excessive runout. Hard spots are another common reason for this type of wear. The disc may get somewhat distorted or warped if the lug nuts are not torqued properly or evenly. This may also be due to dirt or rust that has built up between the rotor and the hub. Pulsations in the brake pedal can be felt if there’s uneven wear on the brake disc.
Brake pads wear out faster than brake discs/rotors, which last about three times longer. Brake pads can last anywhere between 30,000 and 70,000 miles. Some would say, however, that on average, their lifespan is about 50,000 miles, though some may go as far as 75,000 to 100,000 miles. A lot of factors affect the condition of brake pads. These include the kind of brake disc and pad used, the driving style, road condition, type of vehicle, and brake service/maintenance. Brake pads may wear out faster if the vehicle is mostly driven in an area with stop-and-go traffic as opposed to vehicles that usually travel via highways. Hard braking and frequent stops can take a toll on the brake pads.
A bad rotor or disc may cause some low grinding noise or any unusual sounds when you depress the pedal. You may also feel some pulsations. Abrupt stops instead of smooth halts are another common sign. If you experience any of these, take time to check the brakes. If you find some ridges, scores, or any form of damage on the brake disc, then it may be time to have this turned or replaced as needed.
When changing the brake pads, it’s best to use some brake silicone lubricant to help parts move or work smoothly. Graphite-based anti-seize compound is another option for this. Some would change the rattle clips as well, instead of just cleaning them. Take time to check the brake discs/rotors to see if they need to be resurfaced or replaced. Even with new brake pads, optimum braking performance can’t be achieved if the brake discs are not in their best condition anymore. Braking efficiency will suffer.
Common symptoms would have to be the strange noises you hear when braking. These include grinds, clicks, or screeches. Brake pad wear can also be the reason for having a pulsating brake pedal. Vehicle leaning to one side even when the steering wheel isn’t turned is yet another hint that the brake pads must be checked. Upon visual inspection, you may find out that pads are already too thin. Deep grooves and scores in the brake disc can also be a sign of brake pad wear. In any case, you may have to change the brake pads along with the brake discs (or have the discs resurfaced instead).
When checking the rotors, see if there’s any groove or score. If the hollow is over 0.5mm, the disc needs to be turned or replaced. The disc surface can reveal a lot of things about the condition of the brake disc. While it’s quite usual to find minor cracking on the surface, deep cracks shouldn’t be ignored. Other signs of visible damage on the disc may include glazing, rust, heat spots, and pits.
A good number of home mechanics have attempted to do some pad-slap repairs. Some were successful; other didn’t end well. This is not highly recommended for all since this repair isn’t a long-term solution. Eventually, you may end up still considering replacing both brake parts.
- When I depressed the brake pedal, I felt some pulsations. I then checked the brakes and found some of the discs to have uneven wear. What makes brake discs wear unevenly? What are the triggers?
- Do brake pads really wear out faster than brake discs/rotors? What’s the average lifespan?
- What are the symptoms of a damaged or worn-out brake disc or rotor? I want to be able to tell if something’s wrong with the disc even when I’m just driving.
- I’m attempting a DIY on my brake pads. Do you have any good tip when changing the brake pads? I have everything I need here. I just don’t want to miss anything.
- How can I tell if I have bad brake pads and probably need a new set of pads or even a complete Chrysler brake pad and disc kit?
- What are the signs that would tell me when the brake disc/rotor already needs to be turned or replaced?
- Are pad-slap repairs a good idea? Or would it be better to just replace the brake pads and disc?
