Do yourself a favour. Chuck all that rubbish and get yourself a hydraulic one. It takes about 5 minutes to fit (3 screws) and you'll never have to look at it again in the lifetime of your bike, while you get consistent, controllable and reliable braking, better than what you had before. They're only about £20.

Here with two types of brake switches if you need them:

If you find the performance of your new hydraulic brakes not up to par, which can be down to how fat large you are when coupled to a heavy bike, speed etc. All of which can overwhelm the brake and .... lets just say that doesn't usually end well.

You can improve your brakes performance by simply fitting larger rotors. If the bike came with 160/160, you can up it to 180/160 or 180f&r just by changing the brake's mount- which themselves only cost a couple of quid.

Im sure Saneagle will talk you through any assembly/fitting process. He once worked in a bike shop ;)

As to your other dilemma, well its mechanical innit ? only going to be one of two ways it goes in, so trial and error is going to take you seconds to find out which side is which.

Build it A way works. Build it B way, doesnt work

The Aliexpress one is £17 for just the front brake with the SM connector and long long lead, and £22 for one with the red 2-pin julet connector with a short lead. Make sure that you get the right one. Some bikes have the orange 3-pin Julet connector with the short lead.

The Ebay ones are about £23, but they don't have switches in them. If you only replace the front brake and you have a switch on the back one, that's no problem because you only need a switch on one brake.

To fit a hydraulic brake, its as simple as remove the old lever from the handlebars, which means pulling off the grip first. Slide on the new lever and tighten the one screw. The caliper will be hanging on the hose, just put it in position on the disc and caliper adapter and insert the two screws. Don't tighten the screws yet, leave them a bit loose. Pull the brake on hard, and while you hold it on, tighten the two screws. That's it. You won't have to look at it again for years. There's no need to adjust or service anything until the pads wear out, which will be in about 5,000 miles. The pads in hydraulic brakes don't wear fast like the ones in cable brakes.

If you want to be certain about all this show some pictures of your bike. It needs to show the whole bike so that we can see the height of the handlebars and the brake cable routing, and another to show what's on the handlebars. Obviously, if you have very high handlebars, you'll probably need a brake with an extra long hose.

I'm still a bit confused with all this, as don't you need front and back hydraulics brakes then or just front, as you say on ebay its £23 but thats just for a front set right side handle bar.

also on Aliexpress it says this just for a front brake and rear is £19.82 as I have a short 2 pin lead from brake levers to connections at front of bike
