Centre bolt: For Front Centrepull Brake (Universal 61)
Looking for the above before I buy and start filing away at a normal headed bolt! Rough spec below. Many thanks.
Needs to be for front so should probably be a min. of 50mm or so long.
Threaded section of bolt approx. 6mm diameter.
Section of bolt that fits through hole on brake arm can be 6.5 - 7mm diameter. Proprietary shaped hole so can file flats on top and bottom.
Depth of bolt head, around 3.5mm
Have a spare front one if anyone needs one or wants a swap.
