PETCHOR HB-100 Line Pulling Hydraulic Disc Brake Calipers，Mechanical Disc Brakes for MTB, Mountain Bike, E-bike and Electric Bike 2PCS Front/Rear Black/Red/Gold (Purple)

These brakes are a nice upgrade from the ones that came with my e-bike. The mechanical disc brakes it came with were not that good at stopping, and I did want them to work when I really needed them. These brakes are very nice, strong, quiet, and easy to install. In reading the other reviews it sounds like every bike installation will be a little different. My rear caliper went on in a minute but the front took more time to figure out the best mounting spacers to use. The only thing that I had to do was cut the cable ends because the OEM cable adjuster on the caliper was a different size. Not a problem just threaded into the new adjuster and crimped on a new end. I have to say that I'm surprised at how much better they work then the all mechanical ones. I hope they last a long time. I would definitely recommend them 👍Remember you have to take the time to properly install and adjust them.

It seems that the rear caliper bracket works on each rotor as you can see in the picture.I installed the front first and it works and fits fine. The rear is not the best picture but there is at least a 1cm gap that needs to be addressed either with a spacer or lots of washers.If you order for the Jetson I suggest getting two rear calipers. The calipers themselves are identical but the mounting brackets are shorter for the front and will not reach either the front or the rear. Hope this helps other Jetson ebike owners with crappy brakes. These' ones seem to work better than the OEM ones. I've only done a very short ride so long term, who knows? Zero instructions as well. I did the front first with the bracket that fit and was pleased, then went to do the rear, no beuno.

These brakes are a nice upgrade from the ones that came on my e-bike. The mechanical brakes it came with were pathetic, weak, and made all kinds of grinding sounds when you applied them. These brakes are nice and strong, quiet, and very easy to install. I put them on my wife's Heybike which had 160 mm rotors, and I put these on my larger fat tire e-bike with the 180 mm rotors. I did not need the mounting brackets that came with the calipers and simply left the OEM mounting brackets on the bikes and mounted these calipers to the OEM mounting brackets. Super easy to install.

After getting my first ebike, the mechanical disc brakes did not have the positive stopping performance that I, or anyone for that matter, could depend on in an extreme situation. I carry tools which can add a lot of mass to a "downhill projectile" (especially since that bike does 40+ without pedaling). I love these brakes. Installation is relatively easy, patience is required for optimum adjustment. I, in fact ordered a set of these for my new ebike before it arrived and didn't even ride it until these brakes were on it.The best analogy I can offer is that "my bikes now stop as if they are performance cars."
