While disc brakes tend to last anywhere from 30,000 to 50,000 miles, the length of time brake rotors typically last depends on several different factors. These factors include how often the brakes are applied, how hard they are applied, the weight of the vehicle and how often the brakes have been serviced. Continue Reading.

Two-piece floating brake rotors do not do well in areas where salt is a standard winter road treatment. The rotors on a vehicle can last anywhere from 30,000 to 70,000 miles and sometimes more. A licensed mechanic, such as one from YourMechanic, can evaluate the rotors and advise you on their status; they may not need to be changed as often as the brake pads. Like brake pads, they should be replaced in pairs.

They also don't wear out the brake track like rim brakes, rotors are cheap. The rotors only last about 2 years if you're an average rider, plus the pad issue. A rim will last easily 40,000 miles. So lets say you ride an average of 2,500 miles a year, that's 16 years on a rim.

If the brakes are hydraulic,air may have gotten into the system and they may need to be bled. I commute about 10 miles round trip,haul groceries with my main commuter,and have used it to play bike polo. I've been getting about 8 months to a year out of my front pads,and about a year to 14 months out of the rears. 75 miles is way too short unless you've been doing some kind of racing,riding in really bad conditions,or have been seriously dragging the brakes down steep hills.

That's $775 in brake parts over 40,000 miles, I doubt the average cyclist spends $775 per rim. Now how long does rim pads last, Salmon Kool Stops will last at least 10,000 miles and probably a lot longer but lets go with 10,000 and at $14 which mounts to only $56 in brake parts over 40,000 miles. But we left out one important fact, disk brakes require a lot more attention than rim brakes.

Belting down big hills and using the brakes a lot will wear them out quickly. Bimbling around town isn't really going to wear them out that fast. I've met people who've worn out a set of disc pads in a single day and I've worn out a set of rim brake pads in a 100 mile ride due to bad weather.

November 30, 2015. Brake rotors, sometimes called discs, are an important component of the braking system on any vehicle. The brake rotors are the part of the braking system that gets clamped down on by the brake pads, stopping the wheel from spinning.

Unless they gave you some kind of guarantee, it's on you. I don't have disc brakes on any of my bikes, so I don't know how long it takes to swap pads there, but I can do it on any of my cars in less than half an hour for both front wheels.

How long do Shimano hydraulic road disc pads last? I've been riding very roughly 100 miles per week on a new bike since the end of May. The rear pads are completely worn down.

Quoted: 0 Post(s) Just like rim brakes, conditions are a big factor as well as how much braking you're doing (as in long descents). I've worn out disc pads in a day of resort riding in wet and sandy conditions. I've worn out a set of rim brake pads in a single race, too (horrible conditions that day).

The disc brake pad lasts for 30,000 to 50,000 miles.
