Title: Basic stuff, question 1 - coaster brake
Post by: nhoj on March 07, 2008, 07:33 PM
What does a coaster brake actually do? BITD I thought it let you do a roll-back without peddling backwards, is that right, is that all it does? :-\

P.S.  Never really thought about it much in the last twenty odd years untill some new skyways arrived from ebay today with a coaster fitted :D

Yeah, you do roll back without pedalling as long as you 'set' the coaster first.  To do this, you crank backwards a tiny bit. Dont do this and you'll pedal backwards as normal.

Crank backwards a little harder and you'll apply the brake. This is true whether you're going forwards or backwards.

A coaster hub isn't a ratchet like a freewheel is, the insides are completely different.   :)

The coaster has to be anchored to a fixed point if you want the brake to work. If the frame didn't have a coaster bracket then the done thing was to use a seatclamp to anchor the coaster arm to the frame   :)
