Exacerbated by a reduction in use but delayed by a reduction in use, my rear V-brake on the singlespeed is gummed to the point of needing to be replaced, as it has to be manually re-opened after use to stop it grabbing the wheel. I'm going to get one the same as the one on the front which is still working, but does anyone have any recommendations for brands/models of cable-driven full-size V-brakes which are suitable for use with Edinburgh? Front one looks to be something like Shimano Deore LX.

Yeah Deore is rugged. I may have a pair lying about.
Odd that the unit has seized though. You can usually batter them apart, emery paper the crud off and ride again.

“gummed to the point of needing to be replaced“
Sounds liked it needs cleaned.
Unless u mean gubbed??...

The arms will move away from the rim when pulled with fingers, but not when pushed with spring. Spring still springy but of insufficient sproingpower to overcome the determined roadglag. The bit which gets gummed does not seem to be a user-accessible area, which is why I was wondering if it's possible to get a level of brake which can be cleaned effectively enough for it to be worth the extra investment, like paying a bit more for a rear mech which lasts two years rather than one and has hex-head adjustment bolts rather than Philips.
Front brake on geared bike is of the same type and also gubbed, though doesn't yet make the same creaking/scraping sounds as the rear one on the singlespeed. Rear brake on geared bike is fine. Working brakes say XT or LX on them. Gubbed brakes are both Avid Single Digit but I'll need to search my electric receipts to see which digit. In both cases it's the wire-clamping side which makes the worst noise and sticks more firmly.

I've found that my v brakes could be disassembled to a very large extent, so could usually be recovered from their roadglagged state. Might be worth an evening?
The poll didn't have my preferred option of rags/paper towel, scraping and copious grease for reassembly.
But my brakes are very old now, so I don't know if that applies to modern variants!

What is their manufacturer and type designation?
I will put both working sets on the singlespeed for now and order some more for the other one, which will hopefully arrive in time for me having enough time to put the spikey tyres on at the same time. Evenings are generally filled with domestic tasks but if I put the children in different bits of the house on Friday afternoon they might behave sufficiently to give me time to remove two pairs of brakes, refit one and badger the pads into the right place. I think all the old sets of gummed brake arms are somewhere in the loft, so I'll fish them out to ensure I don't get any more of the same sort (nor any Avid Single Digit) and shall post them to see if anyone has any non-destructive ideas for separating the inseparable bits.Posted 3 years ago #
