When should I replace my bike rotors?

Disc brake rotors usually last so long that many people treat them as ‘fit and forget’ components. However, manufacturers provide minimum thicknesses for their rotors. Shimano recommends that its rotors, which start out 1.8mm thick, should be replaced when the braking surface has been reduced to 1.5mm.

How do I know if my rotors need to be replaced?

When Should They Be Replaced?

How long do bicycle rotors last?

But as a result of these physical demands, it is a good idea to check them for wear regularly. Disc brake rotors will typically last through 2, maybe 3 pairs of brake pads (pad material and riding conditions influences this), but it’s never a bad idea to add a thickness check to any regular maintenance schedule.

When should Shimano rotors be replaced?

Braking erodes material off the rotor depending on the riding conditions, rotors will typically last through two or more sets of brake pads. When a SHIMANO rotor measures 1.5mm thick or less, it’s time to replace it. A new rotor should always be accompanied by new brake pads.

How much do new rotors cost?

Brake rotor replacement costs will cost between $200 and $400 for the parts and about $150 in labor costs. This means that you are looking at around $350 to $500 for a total brake rotor replacement job.

Do you have to replace all 4 rotors at once?

Recommended Services

As long as you have both front disk brake pads replaced and rotors turned or replaced as well, it should be fine to complete the rear brakes shortly after. Although it is recommended by Ford to replace all four wheel brakes at the same time for safety, your idea should be OK.

How do I know what size rotors I need?

Call your local OEM dealer and ask for the original rotor sizes or OEM rotor/pads part numbers based on your vehicle’s VIN number (VIN# is referenced in your ownership papers). The dealership may not tell you the rotor size, but they will give you the genuine part numbers for your vehicle.

How long do disc rotors last?

Numerous different brake rotor designs are available, but they generally last anywhere from 30,000 to 70,000 miles depending on their quality and your driving habits. Fortunately, brake rotors typically don’t have to be replaced as often as brake pads, but they still should be replaced in pairs.

How do I clean brake rotors?

Put down a tray to catch any runoff, then spray the rotor with brake cleaner. Let the rotor dry, then wipe it with a clean rag (no oil on the rag). If some rust remains, apply more brake cleaner and work the surface with steel wool or a wire brush. Wipe off the rotor and finish with a final shot of cleaner.

How do I know if my brake discs are worn?

Natural brake disc wear is relatively easy to detect. When a disc is worn, a burr can be felt at the rim, as the disc only becomes worn where the brake pad is applied. The more pronounced the burr, the worse the disc wear is. Experts use special instruments to measure the thickness of the brake discs.

What happens if rotors are not replaced?

Brake rotor unevenness leads to pad wear, and if unchecked, pulsation with high-speed braking. This means the tires wobble and vibrate, leading to a jerky steering column and to anti-lock brake system failure. Replacement of the rotor is critical in this case.

How much does it cost to replace all 4 brakes and rotors?

The Best in Auto Repair

The average cost for brake rotor replacement is between $323 and $428. Labor costs are estimated between $111 and $140 while parts are priced between $212 and $289. This range does not include taxes and fees, and does not factor in your unique location.

Is it safe to drive with bad rotors?

If you suspect you have warped rotors or your brakes are failing, it is important that you avoid driving your vehicle and contact a mechanic right away. Driving with warped rotors potentially will result in a brake system failure, which can cause injury to yourself and those around you.
