Same price as online retail stores but does not included hose. Description indicates it comes as caliper/hose assembly.

I replace my old worn out failed M6100 front brake caliper upgrading to this new XT br-m8100 caliper. I also had to change out the end of the hydraulic hose inline type fitting in the process with a banjo bolt type fitting that fit the banjo bolt on the new caliper. I also had to bleed the brake after the install. Now my front wheel has the stopping power that was missing than what I had with the old caliper.

Did not coming with hose as description says. Did not come with banjo nut or screw as picture details.

Shimano has been making disc brakes now for more than twenty years and you would think that they have perfected their various line-ups by now, ... but you would be slightly off.Recently, I wanted to surprise my son with a customized mountain bike for doing well in school (and helping some other small kids stand up to a bully). I have often used Shimano's XT groupo in the past with generally good results (id est, ... you get pretty much all the benefits of XTR but at a slight weight penalty and a large price cut) and decided to put the same on his new bike. For the brakes I decided to go with the XT level single-piston calipers and levers as they are often regarded as the "standard" for mountain biking. Plus, my twelve-year-old son only weighs 52 kg, so he has no need for four pot calipers yet.I ordered two sets of brake plus lever for the front and back and received them three days later. The calipers weighed 120.3 grams each and the levers weighed 106 grams each. With official Shimano BH90 brake hose, the front system weighed 252 grams (caliper + lever + hose + brake fluid + mounting hardware, ... but not counting the rotor) and the rear system weighed 263 grams. Everything was in nice, new, official Shimano boxes with only one minor nag, .... Shimano's love of black. Count me weird, but I don't like black. I like Ferrari red. So, I totally disassembled both calipers and subjected them to a chemical bath that removed the black electrostatically applied paint that Shimano had used. I then applied a very high-end ERA caliper paint that can withstand temperatures up to 800 deg F and ended up with beautiful Ferrari red calipers that look about 1000% more Italian. (See photo) (If you decide to paint your calipers, do not use standard spray paint as it will simply melt and run when the caliper heats up.)After painting was completed, setting up everything was pretty easy with the only glitch being that the bleed valve for the caliper is now at the very bottom/back. This makes bleeding the brakes on the back tire fairly easy but reaching down under and trying to get the syringe tubing for the front caliper while turning a 7 mm socket wrench is a right and royal pain in my throne padding layer. (Note to home mechanics; You will want a 7 mm socket wrench to do a full bleed if you don't already own one.) Why Shimano could not put the bleed valve on the side as they do in many of their cheaper disc brake calipers is a mystery to me. For bleeding, I ditched Shimano's official 22 step method and used the far better (Daniel) Bernoulli suction method of a syringe to force Shimano mineral oil through caliper and lever, ... and up into the bleed cup. I would then reverse and pull (using suction (and a partial derivative from Dr. Bernoulli) to suck air bubbles back up into the syringe. All the while I used the syringe, I also occasionally pumped the lever to release extra trapped air bubbles. After less than thirty minutes I was done bleeding both brakes and tightened both bleed valves.How do the M8100 calipers work? Almost exactly like the M8000 calipers, ... which is to say dependable but not superior. Even when fully bled correctly, you can still pull the lever about 30% of the way to the handlebar before the pads bite. I would prefer a better system where you pull 10% and the brake pads bite more quickly. Also, the worthless "Servo-Wave" screw on the lever does squat. As it is stock, it is a decent and reliable caliper but not something special. About the same as many of SRAM's offerings but not generally as nice as some of the higher-end Hope brakes. But I am never one to do anything stock, ... so, of course me being weird calculus-loving me, I decided to do some custom machining to the lever so the Servo-Wave screws actually do do something now.In the end, my son now has much better functioning and customized XT levers and calipers that work far better than what came stock. Even more important, he learned something about Daniel Bernoulli, fluid dynamics, a bit of calculus, and machining.How do I rate the stock XT BR-M8100 calipers? About four out of five stars. Perhaps the most damaging thing to say about these M8100 calipers is that there is absolutely no reason to buy these over Shimano's SLX or Deore line-ups (except a tiny bit of weight savings). Unless you have money flowing out of your a##, go with Deore and get, ... not 95%, .... but 100% of the M8100 abilities but for far less. If Shimano would take a look at making a few small changes (including moving the bleed valve and fixing the worthless Servo-Wave) they could easily turn these calipers into five star products.

The best brake caliper for the money! Just what I ordered.

Muy buena calidad viene con pastillas metálicas J04c fácil instalar si ya tienes la manguera bh90 ojo no viene incluida. Importante hacer purga o cambio de líquido luego de instalar
