lechatnoir Posted April 10, 2019 Share also clean the rotors. they;re likely heavily contaminated form being touched and handled.Use some Isopropyl alcohol ^^^^definitely this and try sanding the pads on a flat surface. remember to bed the brakes in again when you're done Link to comment Share on other sites More sharing options...
MrJacques Posted April 10, 2019 Share This might be better than the levers that are currently on there? https://bikemob.co.za/products/shimanoef500shiftbrakeleverset-7speed (I have a similar set on one of my bikes) And there does seem to be options for 7 speed shifters: https://www.buycycle.co.za/mountain-bike/components/shifters/shimano-revo-shifter-set-3x7/ A better quality cable might also help.

Martin PJ Posted April 10, 2019 Share If you don't mind waiting two months buy something off Aliexpress.com Looking at about 40 dollars for front and back set pair. I bought some many years ago to replace cable disc brakes which were always poor, and still using them. They are shimano and work very well. Some entry level brake.

porqui Posted April 10, 2019 Share Strip them completely and give them a thorough service and replace cable inner and outers.Pay attention to pads that they are not contaminated. Link to comment Share on other sites More sharing options...
Longbarn Killer Posted April 11, 2019 Share So, the consensus is to give them a good clean and replace cable. I'm gonna do that on the weekend. If there is no improvement, I'm going to look out for a set of hydraulic brakes on the hub. Link to comment Share on other sites More sharing options...
droo Posted April 11, 2019 Share I'd put money on glazed or contaminated pads. Replace, clean rotors with alcohol, bed them in properly and you're good to go. Link to comment Share on other sites More sharing options...
