front disc cable

[scootcoot]

Hey folks ! been having loads of trouble getting my standard disc brakes to work efficiently on my TV2 , stripped it down cleaned all put brand new sintered pads in and still not great !!! my question is ; could it be the cable ? adjuster and grub screw tightened up and backed off a bit but the cable feels stretchy when pulling in ? do disc brakes need a special stronger cable ??

disc brake on a TV2?- I assume its a standard TV3 item on a TV2.

Original disc brake set up did have a thicker inner cable as standard to counteract any "stretching" when in use. However, there were issues of "stiffness" in operation, and the thicker inner was soon dropped in favour of the standard set up.

Having said that, some inners do stretch quite badly in use- mine was bad on my TV3. I simply fitted another inner and this cured the problem.

With the disc set up, everything has to be working correctly for it to operate efficiently.

try reverse pull loads better ,if you want a thicker inner scooter restorations hope this helps

sorry , its a TV200 , and using the reverse pull set up ! might be a crap cable then ! ill try another tomorrow !

On one of my TV's I'm running:-

1) Friction free cables
2) reverse pull set up
3) Sintered pads from Scooter Restorations

Front brake is very good indeed although I did find the sintered pads need a while to bed in..


AS I said above, everything needs to be spot on for the disc brake to be effective

When you first put the pads are they generally quite poor at stopping till they bed in ?

is the disc floating freely on the three pins?

Yes- I wasn't impressed. However after 10 miles or so of driving they quickly improved, and now are very good indeed. Only criticism is a spot of "squeel" at times- I need to use a spot of "Coppaslip" when they're next apart

One thought- I used some fairly rough "Wet and Dry" on the disc itself to roughen it up- worth doing IMO

a well set up disc brake is just as effective in general road use as a hydraulic monstrosity. something that was pointed out to me recently is the coils in the outer cable. some of the tighter coiled ones with spring about 0.75 mm dont work well as they compress in use and lose a few mm's of travel. the wider coiled outer ones with 2mm coil widths are much much better with a more immediate reaction time. i bought a very heavy duty outer with very little compression loss from Armandos scooters in sheffield. these are sourced in Puglia near their fathers house and are used for argricultural machinery and Apes. Every bit helps when you get a hatchback pilot turning right with her phone in one hand and her lipstick in the other and her indicator near neither!!
