FAQs— Lincoln Brake Disc
- What are some of the basic warning signs that would alert me when my Lincoln brake disc is already in need of replacement or repair?
Among the warning signs that your Lincoln’s brake disc requires attention are squealing noise that seems to be audible every time the brakes are applied, grinding or growling noise which indicates that the pads are already worn down and scoring the rotors, as well as vibration felt in the brake pedal, the steering wheel, and/or the seat when applying the brakes.
- What’s the advantage of spotting a brake disc problem at an early stage? Does that mean I’m spared from the cost and the hassles of brake disc replacement?
Much like the brake pads, the brake disc also has designated minimum specified thickness. If you’re able to spot the problem early enough, you can have the disc turned or machined to make them work like new again without actually having to purchase a new unit. If you continue to ignore the warning signs, there may not be enough rotor thickness left, so resurfacing will no longer be an option.
- A friend told me that since my Lincoln comes with ABS, the more I should be mindful of the thickness of my Lincoln brake disc and pads. Why is that so?
It’s very dangerous for a car equipped with anti-lock braking system to let the brake pads or disc wear down past the minimum required thickness. You see, such brake system comes with sensors that notify the driver when the brakes are too low, and driving your vehicle continuously will damage the said sensors.
- Does brake squeal indicate a need for brake disc replacement?
Some brake manufacturers equip their products with a warning mechanism that creates a squealing sound when the pads are worn out beyond the minimum thickness. However, that squealing sound can also be heard when the brake material interacts with extreme temperatures or humidity or as the pads deal with slight rust on the disc surface. Allow your brakes to warm up. The sound should disappear as the rust wears off or once the moisture in the disc has evaporated. If you continue to hear the squealing noise every time you step on the brake pedal, have your brakes checked as soon as possible as that noise usually indicates damage on the brake disc.
- My ride employs a captive rotor, and I think it now needs machining. The problem is that I can’t take it off the brake assembly to bring it to the shop that has brake lathe. What are the available options for this type of disc?
You can still have the disc resurfaced by using on-the-car brake lathe. This machine resurfaces the rotor without a need to take it off the brake assembly, making it perfect for a captive rotor that’s held on by the hub. Even with the brake caliper and the wheel removed, this rotor can’t simply be taken off. If you really want to take the rotor off, you will need to disengage the hub assembly. Using an on-the-car brake lathe can be a labor-intensive process, and you have to make sure the rotor still has enough metal left even after resurfacing.
- I’m really bothered by the rust I see on my Lincoln brake disc. Any tips on how I can get rid of this?
Rust isn’t really something you should worry about, particularly if it’s just surface rust and positioned on the area where the brake pads and the disc meet. As you use your brakes, the pads will just rub the rust off. If the rust is seen on the rotor hats, or where the wheel studs pass through and the area where pads don’t come in contact with, you may need to sand it. You can also try attaching a wire brush on a drill and brushing the rust off.
- My friend had a difficult time detaching the brake disc of his car from the wheel hub due to rust. What can I do if the same thing happens to me during my DIY brake disc replacement?
The brake disc really becomes difficult to remove if it hasn’t been replaced or serviced for a long time. You may hit it with a hammer to loosen its attachment to the hub. Or rather than directly hitting the rotor with the hammer, try to soften the blow by holding a 2x4 piece of wood against the rotor. Also check if the disc is held to the hub by additional fasteners.
