2 Pairs Brake Pads for TRP Tektro Shimano Deore Br-M575 M525 M515 T615 T675 M505 M495 M486 M485 M475 M465 M447 M446 M445 M416 M415 M395 M375 M315 M355 C601 C501(Resin,Semi-Metallic,Sintered Metal)

A+ pads. Didn't fit my Lectric XP 3.0 but that isn't corkis fault. They will fit if you grind them down a little. Great stopping power and very quiet. I highly recommend the blue pads for longevity and performance. Corki is telling the truth when they described the performance. I expect these pads to last anywhere from 2k to even 4k miles.

Updated 3/30/2023 for Sintered Metal version The new compound is fantastic! There were minor things on the Copper-Based that were easy to live with for the performance. First, the brake material was thinner and backing plate was thicker than OEM. Overall they were under 4mm total. You got less mileage. Also, the Copper-Based did take their toll on rotors. My rear stock TR-24 (180-24) rotor lasted just over 2,000 miles before it was approaching the 1.5mm replacement point (1.55mm at thinnest point). The Sintered Metal have more braking material, a backing plate closer to OEM, and an overall thickness just the tiniest bit over 4mm. Significantly more mileage (over 900 versus 500-600) with all the things we loved about the Copper-Based. The edges do seem a little more brittle, so go easy on wheel changes! Still, I have to say the Sintered Metal are my choice now for this pad form factor. Full disclosure: I was provided a set (4 pads) of Sintered by Corki when I inquired about the compound change. I have since purchased a set (4 pads) as well. Original review of Copper-Based: Purchased the Copper-Based pads to replace A10.11 OEM pads for hyraulic Tektro HD-E 350s on an Ariel Rider Kepler ebike. I had used 0.2mm of the original pads and had enough of their turkey gobbler call when heated up. These Corki Copper-Based pads perform superbly. No more fade and odd sounds by heat buildup. They bring my 26" x 4" wheels, on 90lbs of bike with super grippy slicks, and 225lbs of me, to a quick, controlled stop from 32mph. Whisper quiet stopping with no fade. Do not wait to replace cheap OEM pads. Put these in now!

These pads are a really good value. Not expensive, fast delivery and fit my Shimano hydraulic brakes perfectly. They worked great on the trail after installing. No squealing. Good feel. My only knock on them is that the included cotter pin is a little bit too short. I had to reuse the old one.

These are the best pads I now have the best stopping performance ever I now feel safer

These pads make a difference over OEM pads. I own a Cyrusher Ranger, with accessories it weighs about 87lbs plus my 200lbs. The OEM pads were not giving me the confidence while downhill breaking. These copper pads are listed to replace Shimano Decore 1-5 and they fit perfectly. After properly seated the brakes seem to be 40% stronger and just as quite as organics. I'm using them with Logan E500 hydraulic breaks. Best bang for the buck. Install took 20 minutes F/R.

My original brake pads were evidently resin pads and, over time became less and less effective. The front brake started sounding like a turkey gobble. I took it apart and cleaned the rotor and pads and the scuffed the pads with sandpaper. Then took it for a ride and bedded the pads. Initially, it seemed like the problem was solved but a few weeks later the turkey gobble was back. I ordered these Corki pads in semi metallic and put them only on the front. Then took it for a ride and bedded them in. Wow! What a difference! These pads are super effective. Yes, they make some noise but only the sound of friction, quiet compared to what I had before. These are what disc brakes should feel like. I will put the second pair on the rear soon. I can't speak for durability but I am very pleased with these pads.

I give these three stars because they fit my Rad Runner, and they stopped me when I pressed the lever, and they might be perfect for someone who rides less often. I ride 9 miles a day to get to work and back, the Tektro brand breaks lasted me about a year. I thought I'd give these a try earlier this year when my last set wore down. I changed them on a Monday, by Thursday I was already adjusting the breaks, and this seemed to continue a trend of 4-5 days between adjustment. This left me scraping metal before 2 months. The price is good, and if you're not going to be using them as much, it may be worth it, but for me the labor is not worth it. It is nice that they came with a new cotter pin, and they're just as easy to install as the name brand, but the amount of times I had to hop off my bike and adjust the placement of the breaks, and then replace the breaks compared to the name brand, they just aren't worth it for me.

Why did you pick this product vs others?: This compound was advertised as having the best stopping power. Brake quality: Best stopping power my 90 lb electric bike has had since I bought it 2 & 1/2 years ago. Very impressive. A little noisy.
