10 best disk brake rotors

Disk brake rotors, also known as brake discs, are a crucial component of a vehicle's braking system. They play a key role in slowing down and stopping a vehicle. Here's what you need to know about disk brake rotors:

  1. Function: Disk brake rotors work in conjunction with brake pads to create the friction necessary to slow down or stop a vehicle.When the brake pedal is pressed, the brake pads clamp onto the rotor's surface, generating friction and reducing the vehicle's speed.

  2. Material: Rotors are typically made of cast iron, but they can also be composed of composite materials, such as carbon-ceramic, which offer advantages like reduced weight and improved performance under extreme conditions.

  3. Designs:

    • Vented: These rotors have vanes or fins in between the two friction surfaces. Vented rotors are designed to dissipate heat more effectively, making them suitable for high-performance or heavy-duty applications.
    • Solid: These rotors have a single, continuous surface without vanes. They are often used in lighter vehicles or for rear brakes.
  4. Slotted and Drilled Rotors: Some rotors have slots or holes on the surface. This design can help dissipate heat more efficiently and prevent brake fade. It also allows for better water dispersion, improving wet weather performance. However, it's worth noting that slotted or drilled rotors can be more prone to wear.

  5. Wear and Replacement: Over time, brake rotors can wear down due to the friction from the brake pads. It's important to regularly inspect rotors for signs of wear, such as scoring or grooves. If a rotor is worn beyond its specified limits, it should be replaced.

  6. Resurfacing: In some cases, rotors can be resurfaced to remove minor imperfections and provide a fresh, even surface for the brake pads. However, this is not always possible depending on the extent of wear and the rotor's thickness.

  7. Minimum Thickness: Manufacturers specify a minimum thickness for rotors. If a rotor has worn down to or below this limit, it must be replaced to ensure safe braking performance.

  8. Brake Rotor Warping: Excessive heat or hard braking can cause brake rotors to warp. This leads to a pulsating sensation when braking. Warped rotors should be either resurfaced (if within specifications) or replaced.

  9. Matching with Brake Pads: It's important to use compatible brake pads with your rotors. Different types of pads (e.g., ceramic, semi-metallic) have varying friction characteristics, and using mismatched components can lead to uneven wear or reduced braking performance.

In relation to Brake System, Replacement Parts, and Automotive, understanding disk brake rotors is essential for maintaining the safety and performance of a vehicle's braking system. Regular inspection and timely replacement of worn or damaged rotors are crucial for safe driving.

User questions & answers

Question: Is it compatible with BR-M447 caliper
Answer: Sorry, China
Question: Dimensions of mounting holes for both inner and outer positions
Answer: The unit will distill approximately 3 liters per 3½ hour cycle, so about 4¼ gallons in 12 hours. To order (and support a family-owned small business) please click "See this seller's offer" below. Thanks!CoolShinyStuff --------------------------------------------------------------- V V V V V V V V V V
Question: If I am going from a 160 mm to this 180 mm rotor do I need to change the bracket adaptor on the bike
Answer: Just under one tablespoon of Himalayan salt (1tbl-sp per gallon... this produces .8 gallon per batch; this salt is pink in color... raw form) will balance the water (alkalinity) and add back 80+ essential minerals. I surprised no one suggested that yet.
Question: Can these be used with sintered/metallic pads
Answer: Home distillers pretty much all work the same way, just the mechanism setup is different. I couldn't find a home distiller with "2 phase heating process," I did find the term in industrial distilling

User questions & answers

Question: im using 160mm disks. can i replace them with these
Answer: Upper right side (boiling chamber side) gets hot to the touch. Treat it like a drive or oven with kids. Don’t touch. Bottom is tank so it does not get hit and will not affect counter top
Question: im using 160mm disks. can i replace them with these, ....180mm
Answer: No
Question: Going 160 to 180 mm how do i figure out whether or not i will need an adapter and also what size adapter i will need
Answer: The reset button is to protect the product from being burnt out, and to protect it from overheating to prevent the machine from working after the water distillation is complete, which is very dangerous. If you want to stop during use, you can directly use the ON/OFF button.
Question: do these work with tektro aries brakes 180m
Answer: It doesn't seem possible that only running the distiller would account for that much of an increase. The distiller is rated as using 750 w, so if it is running constantly 24/7 this would increase your energy usage by 18 kw per day, or 540 kw per month.

User questions & answers

Question: you sale the pair of disc or its just one disc
Answer: While the water is funneled through a glass insert, the outlet on the glass insert is shorter than the plastic outlet, so as the water drips from the glass insert, it contacts the plastic funnel outlet briefly. Also, on the inside of the distiller, the stainless steel tube the steam rises up through has a non-metallic gasket that some water may contact and drip back into the distiller tank.
Question: Do these take metalic pads
Answer: I used a watt meter, it cost between 35 cents to 50 cents for 5.5 hours per gallon, at the most expensive it will cost 50 cents at worst, if your electricity rate is very high. What I do is I pour boiling water into the pot first (because I have a gas stove), which saves 40 minutes from producing 1 gallon.

User questions & answers

Question: Does it come with two of them
Answer: I do not have a fluoride tester but the research I have done says it does.Sodium Fluoride's Melting point is 993 °C (1,819 °F; 1,266 K), and its Boiling point is 1,704 °C (3,099 °F; 1,977 K)Calcium Fluoride's Melting point is 1,418 °C (2,584 °F; 1,691 K), Boiling point is 2,533 °C (4,591 °F; 2,806 K)In short the Distiller does not have the heat required to boil the Fluoride in water.
Question: What is the coating on the front of the new pads
Answer: The manufacturer recommends changing the filter every 30 gallons. We sell a 12 pack of filters for $14.95. The unit comes with six filters. It just has this one filter.

User questions & answers

Question: Does it need to tune before replace
Answer: Yes, but you will need a spacer for your caliper to clear the taller rotor. Like Shimano disc brake adapter Disc Brake Mount SM-MAF180 Front PM/PM
Question: Are they sold in pairs or singles
Answer: About 240g
Question: Is this just one front rotor? Just making sure before buying
Answer: I was not sure either, I just counted the screw holes and took a chance and it fit.
Question: Is this just one rotor or a pair
Answer: These will work with any disc brake setup however, you will need the proper spacers for the larger diameter.
Question: Are screws incluidos
Answer: You should check with the BR-M447 manufacturer. You should be able to find out what you need for that make and model of caliper, then compare what you need, to what the product is. Best I can offer.
Question: Can this rotor be used to replace an Avid SH1 160mm/120g rotor
Answer: The pattern is standard.
Question: What is the weight of the rotor
Answer: Yes, you'll need the 180 mm adapter. It basically moves the caliper out the 20 mm you need for the pads to fit against the braking surface area on your new 180 mm rotor.
Question: is compatible with tektro 160mm rotor
Answer: I'm using them with semi/metallic sintered pads right now and so far they are working. I don't ride that much only about 6 to 10 miles a week so I haven't put them to a real test, but so far so good.
