Is there anyway i can improve the Zoom disc brakes on my recently purchased CD Sport, especially the front brake, i have adjusted them as in the Woosh instructions, but there still not to good, i'm not expecting Hydraulic performance, and understand there only very basic disc brakes, the old rim brakes on a very very old Raleigh i have are far better, and that bike is at least 30 years old. Other than that the bike is good.

you can replace the Zoom caliper with a tektro Novela caliper from Woosh for about £15, a bit better than Zoom, or go hydraulic

Put only one in, you need to keep the other one for the brake sensor.

It's not worth messing about with it. Get yourself a hydraulic brake. You can get them new for £35 or used for a lot less. It's a simple swap. Once you've tried hydraulic disc brakes, there's no way back.

The pads become easily contaminated especially if a spray oil has been used, perhaps on the chain and the over spray has drifted.
You could try taking them out and give them a very careful flat rub on medium abrasive paper on a flat surface which may help but not for long if they have been "oiled".
Maybe buy a new set and try them before you go any further but make sure the rotor/disc is really clean before you fit them.

This looks a good option , not as expensive as I thought, and maybe within my capabilities. How would I go on with the sensor cables to the brake leavers, I would imagine I would still need to have the motor cut on braking.
Yes he did, just thought it best to fit the pair, I just looked at disc brake sets for e bikes, ouch..very expensive. Will look into maybe just one brake for now. Thanks
There is another thread just up the page about converting a bike which goes into the issue of cut outs with hydraulic brakes. It's a bit complicated apparently....
You only really need the front brake though. With the extra weight of e bikes they're more like small motor bikes in that regard where most of the braking is done on the front wheel. As long as I shift my weight rearwards when I brake hard going downhill it's fine.

It's the front brake that does all the stopping (if your brakes work properly), so just upgrade the front to hydraulic leaving the back one with the sensor. You only need a sensor on the back brake.

There's all sorts of adaptors to fit different calipers to different forks and discs. If you get any of the ones I linked to above, they bolt straight on without adaptors. In the worst case you might have to put some 6mm washers under the caliper to lift it up a bit if the disc touches the top of the caliper. Your disc will be OK - no need to change it. When you fit the new caliper, leave the bolts loose, then hold the brake on while you tighten the bolts. This will centralise and align the caliper.
I have been looking at quite a lot of you Tube clips on fitting Hydraulic brakes tonight, don't get me wrong i do appreciate all the advice but it looks a bit fiddly to me and i would have to get the bleeding stuff as well. I know the Zoom brakes are very poor, and wonder if a pair of Avid mechanical brakes would be an alternative, fitting looks straight forward and i still have the sensor cables connected.

You don't have to do any bleeding. Two screws for the caliper and one screw for the lever is all it takes to fit one. I think you've been looking at the wrong video.
I also had similar thoughts to yours before I got hydraulics, now I wouldn't have anything else.
Unless damaged they may never need bleeding, how many times do you bleed car brakes these days?
Dave.
Thanks for all the advice, after much thought I think im going to stick with mechanical brakes, and buy either a pair of Avid BB5 or BB7 calipers from ebay, may get new discs if needed. I should the be able to keep the original Woosh levers with sensor cables. More than likely a Ebay purchase, tried Halfords this afternoon, no luck.

Want to upgrade my mechanical 160mm disc on my Wisper to hydraulic and came across this on Ebay. What am I missing in the advert? Seems too cheap.
