M375 Brake Caliper 2017

I decided to upgrade my MTB & the brakes were one system I felt deserved an upgrade. I originally had V-brakes, wanted to try disc brakes & felt a pair of SHIMANO M375 Brake Calipers were a good entry level choice. The M375 calipers come w/the mounting bolts (pre thread lockered), washers & brake pads. The installation was straightforward & simple. I installed w/180mm Shimano XT SM-RT86 rotors in both the front & rear. For the front fork, I used a Shimano SM-MA90 post to post adapter & in the rear, a Shimano SM-MA-R180 IS to post adapter. With this setup, the M375’s work awesome. After a couple test rides & adjustments, the braking is strong, even when wet (unlike wet V-brakes). The M375 calipers have 1 moving (outside) pad & 1 stationary (inside) pad when the lever is squeezed. I’ve read & watched some instructionals that recommend placing a credit card or thin shim between the stationary pad & rotor when mounting. Although this works, I found this is not necessary. When mounting the calipers, I installed the bolts hand tight, allowing the calipers to move. I then squeezed the brake lever, this allowed the caliper to adjust itself on the mount, aligning to rotor. I then tightened the mounting bolts, securing the caliper. This will cause the stationary pad to rub the rotor. At the inside of the caliper, if you look through your wheel from the opposite side, you’ll see an adjustment bolt for the stationary pad. I backed off the pad w/the adjustment bolt 1 click at a time, until the wheel spun freely w/out rub. This allows for forward adjustment of the pad as it wears down in the future. Just my 2 cents. If your converting from V (rim) brakes, don’t forget to order/buy new brake cables. Your brake lines are most likely too short to reach the new position of the brake calipers. If you’re looking for an inexpensive entry level mechanical disc brake system, I can recommend the Shimano M375 calipers as a great option. Thank you for taking the time to read my review, I hope you found it helpful.

These calipers are extremely easy to install and set up. I installed these on a rigid single speed 29er that has a damaged hub that causes a slight wobble in the brake rotor. These calipers not only had enough clearance to eliminate annoying brake rub, but they also still have a firm feel and responsive brake engagement within the first half of lever pull. Stationary pad adjuster screw makes adjusting for pad wear easy. ________________ These calipers provide plenty of stopping power. Once I bedded these in with the new rotors, Shimano BR56, they provide enough power to skid the front tire of my mountain bike on pavement and gravel. ________________ These calipers are a great value, especially if you are replacing existing mechanical calipers. At $25 each, these are an exceptional value. They do not come with Universal Mount adapters, but this was not an issue for me because I already had the adapters I needed. _______________ High Quality. Like most items from Shimano, the quality of these calipers is evident in the finish and feel of the item. They don't weigh much, which is good. All surfaces are smooth and precise and they feel solid and sturdy. _______________ My set up includes two of these calipers on Universal to post mount adapters, Shimano BR56 180mm rotor up front, 160mm in the rear. Shimano universal stainless steel brake cabling and Shimano T-Type brake levers. This setup comes up to less than $50 a wheel and produces ample power.

So there's a thing in biking called an Endo. It's short for End Over End, and it's when you brake (or hit something) so hard with your front wheel that your rear wheel leaves the ground. Usually this results in you flipping over the handlebars, which is where the name comes from. However, if you have a good enough brake (both in terms of stopping power, and control of that power) you can control the Endo, and lift your rear wheel without flipping over. That is the fastest way to stop a bike, period, because you can't apply more braking power to the front without flipping, and the rear wheel is off the ground so braking harder with it won't do anything. In a controlled Endo, you are applying maximum braking power for your bike's geometry and speed, so getting a stronger brake won't help you, it'll only make you flip over the bars faster. This brake lets me Endo in a controlled manner, reliably. Therefore, this brake is good enough that a better one won't actually stop me any faster. It's not the most powerful, but it really doesn't need to be. In other news, it doesn't squeak much, is easy to align/trim, and the pads last for ages, even with daily stop and go city traffic. Now, that said, there's a very important thing you should know about this brake. The cable attachment mechanism has a flaw. When your pads are running (very) low, the knob on the side that the cable pulls on to activate the brake can rotate far enough backwards that the cable flexes the opposite way, at its attachment point to the knob. It's hard to explain in words, but if you have this brake, take the wheels off your bike and pull the cable as far as you can, you'll see the flex point, right where the cable end is bolted to the brake. That flex point means that, if you don't replace the pads when they wear down, your cable will bend back and forth to the point of snapping. I had both cables, front and rear, snap on the same day, because I brake evenly with front and back to distribute wear. So, once a month, give your brakes a good pull while looking at the calipers, and make sure that flex isn't happening.

The cam on my brake caliper wore out and this was a perfect Universal replacement. Used to be terrible in the hills and mountains without a good working rear brake but now I have one and if I need to get one for the front I would definitely buy this again comes with brake pads

Let me start out by saying I'm not a mechanically inclined person. I took a chance for $20 to buy this and hope it fit. The previous front brake had those pair of circular pads that were held apart by a V-shaped pin, and they were a pain to work on. I accidentally stripped a bolt putting in replacements and that was it, part of the housing fell down and the front brake was done. So I got this one and crossed my fingers. I can't believe I installed it outside at dusk and it worked. The rotor on the bike is warped and scrapes the pad but that's not a huge deal, the brakes work. It was not easy to thread the frayed brake line through the narrow hole but I somehow did it. The only other issue was that the original brake housing had two spacer washers on the inside part of the bolt threading, and I had to remove them in order to have the rotor come into more contact with the majority of the pad surface area. In other words, if the opposite occurs and the rotor goes all the way inside the two pads and you can't finish attaching the front tire to the bike, then you need to use one or more spacers. I think that if you have done some minor work on the brakes before this is totally doable. It should fit most bikes; like someone else on here said as long as the mounting is vertical then it will fit and it's just a question of needing to use spacers on the end of the mounting bolts or not. The actual braking is fine, you of course need to make the appropriate wire tension adjustment and also loosen or tighten the other side of the pad with the center allen wrench hole until the wheel spins freely. I'm proud of myself lol, I installed this in the dark, first time ever. You can do it too.

Great stopping power from a mechanical brake, this was installed on a Swagtron EB7 ebike and performs way better than the factory one. Comes with pads. They look and perform 3 times its price. May recommend upgrading the cable adjusting screw for a better tool-free tensioning.

I have been using them for about 3 years now they work well and are easy to adjust but they do get in the way of some of my accessories because of the large circle swing arm design.

This caliper must be about 11x more powerful than the no-name unit the local bike shop sold me - which barely slowed me down when squeezing the lever full-force. Am in rough shape as I write this, as I ended my test ride tonight with a spectacular endo. They definitely grab better after a brief break-in period. The first few hard brakes felt about 10x more powerful than my old caliper.

Gute mechanische Bremse mit Kabelzug konventionell bedienbar.

Très Bon frein puissant de caliter qui freine sec en plus il c'est auto réglé l'or de mon premièr essaie j'adore parcontre il l'a fallu que je déssérre l'aipésseur des patins car mon disque était un peut trop épais et j'ai rajouté 2 rondelles supplémentaires pour qu'il ne touche pas le disque dans la hauteur verticalement le levier circulaire et parfait pour avoir la bonne longueur de câble pour la tension j'ai qu'une chose a rajouter excellente caliter pour un prix abordable !

Compré una porque se rompió un tornillo del trasero que tenía, de marca "la pava", lo puse y me dio tan buena impresión que pedí otro para tener otro nuevo también delante y curarme en salud. Una vez probados, debo decir que la sensación de frenado es muy buena, frena con potencia, pero sin ser incómodos. Al revés, se me han hecho muy cómodos y muy seguros. Diría que volvería a comprarlos, pero espero que duren mucho y no haga falta.

Es un buen producto la composición es de buena calidad y enseguida se siente la diferencia del frenado

Looks like original. But when it arrived.. the box was damage due to delivery.
