Hope Open 4 System Rear 165

Advantages: Superior build quailty and maintence free
Disadvantages: Set up is time consuming

...I bought these brakes 6 months ago for my hard tail, I had looked at many other brakes like Hayes and Maguras but they didn't have the excellent quality and stopping power that the Hope M4's have. The brakes came pre-bled so it was just a case of bolting them on and aligning them. This can be a bit time consuming as the pads sit close to the rotor so they have to aligned well to stop any rubbing. Once everything is set up these brakes are virtually maintenance free, only have to replace the pads ever so often. The system stops any air leaks very well, I haven't had to re bleed them in the 6 months i have had them. Superb brakes that stop you in an instance and will not break however many times I crash and land on them.... Read review

Advantages: 4 pot brake, hard wearing, solid build quality.
Disadvantages: Difficult to set up.

...I bought these a couple of years ago and I have never ridden with a brake that is so good. I rode with maguras for a while and when I upgraded to the Hope discs i could tell the difference immediately. these brakes are used by some of the top riders in the world so that obviously shows that they are a top component to add to your bike. Once set up they can be left until new pads are needed, they take a little time to set up however once they are done they are excellent, they do not need bleeding very often as they stop air getting into the system very well. Do not buy any other brake system, this is the best and worth every penny.... Read review

...is somewhat bigger, with options of 165 and 185mm at the front, and 145 and 165mm at the back. Hope have also chosen this brake to be the first to benefit from their new bubble rotor design, the disc itself being a strange lumpy shape instead of round, for no apparent reason. The brake is supplied assembled by the factory, so you don't need to worry about getting brake fluid everywhere, unless you need to shorten the hose. The brake comes with a hose designed for big monster downhill bikes, so my tiny XC bike need some modifications to be carried out. Simple enough, spanner to take the hose off with, knife to cut it, and some DOT 5.1 brake fluid from your nearest Halfords (in the car section, not bikes!). As anyone who has ever bled the braking system on a car will tell you, getting the air out is a pain, although as later found out, it goes... Read review
