When choosing brakes for electric bikes, the most important factors to consider are the braking power, durability, compatibility with the bike's components, and ease of maintenance. It is crucial to ensure that the brakes can effectively stop the bike, withstand frequent use, work well with the electric motor, and are easy to adjust and repair when needed.
kinda need to know if your needing the back or fronts changed, but in any case take them in to qualified techs if your not to sure about your brakes and how to work on them! their your brakes you wanna know that your car is gonna stop when you need it too!!!!
You will have no brake assist, so the pedal will be very hard. You will also have no pressure at the rear brakes. Only the fronts will work without the pressure pump.
The fronts do the most work so the proportional valve sees they get more pressure. That is also why reservoir for front usually larger as well.
Essential parts needed for road bikes include a frame, wheels, tires, brakes, gears, handlebars, and a saddle. These components work together to provide a smooth and efficient riding experience on paved roads.
Impossible to answer from such a short description, but probably you need to tighten the cables one way or another. Try the related links.

I had this same problem with a 91, on mine it was the caliper slides, which allow the brakes to self-adjust.I was able free them up with penatrating oil and then work them back and forth until they worked on their own.The slides are where the mounting bolts go through the calipers. Hope this helps Good Luck.
