I imagine some disk brakes may be a little awkward to BLEED.
Also I guess some HOSES are hard to cut, and if you buy any BRAIDED HOSES, they better be the right length, don't think you could cut those to size EASILY!
Also I guess some of the HOSES UNION (OLIVES), may be useless, whereas others will be easy to fit and perform trouble free.
But I guess with the following tools, for the CALIPER and the BRAKE LEVER RESERVIOR, it should be
initially straight forward to get started!:
Such as: BLEED VALVE SPANNER, PIPE for CALIPER BLEED VALVE, JAR to collect old BRAKE FLUID, SPANNERS (8MM, 10MM, etc), WIRE/PLIER/HOSE CUTTERS, NEW BRAKE FLUID, ALLEN KEYS, SCREW DRIVERS, KITCHEN PAPER/CLOTH (To prevent spillage over disk/pads/rim/bars/stem/floor, etc).
Still guess putting the BRAKE LEVER RESERVIOR housing cover back on, and pulling the brake lever, pressing master cylinder within,
it would be immediately obviously if there was any AIR (Spongy feeling) in the system, or if you had adequately tightened the bleed valve bolt! (If not tight, there would be a leak!)
