The disk brake on my LC is very poor the pads are not worn but I feel the disk may be glazed, I have looked on U Tube and they deglazed the disks using Scotch Pad on the disks and then cleaning with Contact Cleaner, what type of contact cleaner should I use? I assume it is the one for electrical parts?
Any advice please.
Philip.

Focus you efforts on the Brake pads.. remove them then rub them about on some 100 grit sandpaper untill the surface is a smooth uniform colour.
Discs rarely get glazed and when they do rub that same 100 grit on then OR remove them and use an orbital sander on them.
Don't worry, as the disc material is So tough that you will only manage to dull the shine a bit.

Even when working well the LC brake isn’t a patch on modern brakes. 2. The floating and sliding parts in the LC calliper design easily wear and or corrode such that a brake that hasn’t been overhauled recently is likely to only partially operate. 3. ageing plastic brake hoses will balloon under pressure, means lots of work on the lever converts into little brake force at the business end. 4. System design doesn’t lend itself to easy complete bleeding ( although perfectly possible once you know the tricks). so , whilst making sure pads and disc are grease free, plus a scrub up for good measure as above . Make sure all the mechanical actuation in the system is free and working well. |

you wont see any kind of miraculous improvement with the LC2 caipers, its much the same design as the LC, and defo not modern.

The only real way to improve them is update 4piston calipers update master cylinder braided hoses etc a relatively easy and low cost option, the brakes were never that good as new
Even more noticeable if you are used to modern bikes brakes

Has you bike got 1 or 2 discs. As mentioned above there is not much difference between the standard and LC2 caliper.
If using two disc try a 250 master cylinder.
I used a master cylinder from a SZR which I believe is 13 mm diameter.

I had good results with braided hose and EBC green pads on my lc racer. The discs were drilled also which may have helped

Personally I don't think that the 4LO brake set up is that bad to be honest, my bike does have braided hoses though,...regular strip and clean of calipers is what I remember doing even back in the day.
Sure, the brakes on my modern bike are better but the tyres are a lot wider too.
