I've done quite a lot of things on my bike, but still inexperienced with brakes.
My front brake drags a bit (when rolling you can hear it whine, but its pretty easy to push so probably not a big deal)
The brake fluid is probably as old as the hills.
I'm told that these bikes don't have a spring to return the brake pads, instead the rubber mount pulls the pads off the disk when they're not being pushed on. And they're probably gummed up with dust and dirt etc.

How difficult is it to clean the brakes so that they return nicely? is it better to disassemble them completely and do a proper clean/service? Then theres still draining the fluid, disposing of it properly, refilling it, bleeding it.
Is there a nice guide somewhere for this?
If it takes a lot of skill or whatever I can get my mech to do it.

If I do it myself I'll definitely service the front first, and leave the back for a while, just in case I have issues with the front, nice to know you have SOME brakes :)

The NC24 has sliding calipers, some dragging on the disc is normal, most if not all disc brakes drag to some extenet, especially with new pads.

You'll probably find your sliders are dry and not moving, this happens especially if neglected or the wrong type of grease is used.

I overhauled a set of NC24 brakes recently.



Buy all the new rubber seals.



Strip the calipers into pieces.



Caliper cleaned and with a new rubber seal put in for the Slider to go into.. this seal is called the boot seal.



You must use red rubber grease when installing new seals.



Installing the piston seals.



Pistons in



All done.

Then remount the calipers to the bike and put new fluid in the lines and your ready to go
