Shimano 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.

I used a pair of these Shimano calipers to add disc brakes on the front and rear of my mid 80's Trek aluminum frame mountain bike, when converting it into a 1500W electric urban assault commuter bike. The front was easy. These calipers bolted directly to the Suntour suspension front fork I purchased as part of the upgrade. The rear was considerably more challenging. I found a disc brake adapter on Amazon to add disc brakes to bikes without disc brake braze ons, but the universal adapter required a fair amount of modification, custom shims, etc. It also required me to buy the Shimano MA-R mounting bracket. These disc brakes may not offer the wheel locking braking power of hydraulic disc brakes, but they're super easy to install and maintain and they're compatible with conventional cable operated brake levers. I'm not even sure there are hydraulic brake levers for electric bikes with the integrated brake switches in the levers. The stopping power is MUCH better than the old U brakes I had on my mountain bike. Disc brakes are a very nice upgrade and the BR-M375 calipers offer a very good value. The price is very low but the quality is excellent.

Best style mechanical calipers!! Very stronge will locks up them disc brakes no problem

Great value for the money. Very important that you take the time to bed the brake pads in. At first I didn't like them but followed people's advice on taking the time to bed them in correctly and wow I'm impressed. Watch a video on how to bed them. I'm using a180mm Avid G3 rotor in the back and 180mm Teyssor rotor in front. Plenty of adapters are sold to allow these brakes to upgrade your rotors from 160mm to 180mm but I chose the Shimano's just to be safe as I originally had 160mm rotors on my rims. Don't install them and immediately go riding that can be dangerous if you're new to mechanical disc brakes. These are Shimano Acera level brakes and are great entry level mechanical disc brakes. You can't beat the price.

Absolutely 💯 good. Flush mount for 160 rotors and upgrading a bike from rim brake to disc brakes. Good clean well.aligned rotors and this caliper will stop you. I'm 300lbs on a mtbmx and it stops me just fine. I'm definitely buying this again if I'm doing another build.

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.
