Brakes are $350 a set with $15 for shipping anywhere in the US. There is no linkage provided and you have to sign and send him a waiver (funky California law).
I have some and am extremely pleased with their performance. The only negative is that you have to really work and play with them to get the bands to have full surface contact all the way around the drum. He needs to tweak his castings a little bit, but it's nothing a little TLC can't overcome. Mine work REALLY well.
How do A C Brakes compare with Rocky Mountain Brakes? I see a very large difference in price. Are there any noticeable differences in performance?
I'm having trouble with mine and currently have them disconnected. the shoe doesn't follow the curve of the drum and drag. I would like some pictures of installs posted to help clear up whether I've got a bad set or (more likely) I've made some mistake installing. Not saying a bad product, but they haven't worked for me yet. Would like some better instruction on how to set these up than what was provided in the kit. Again, not bashing or bad mouthing, this could be all my issue, but I can't seem to make them work no matter how I set them up with the feeler gauge and following the instructions. Not sure why the curve doesn't line up even after attempting to bend in place to straighten it's too far out.
The AC brakes are the only ones currently being made for the small drum, the Rocky Mt are a large drum setup, with a large drum adaptation for the small drum cars. The large drum brakes do work better due to the larger area.
I also had a bit of a time getting the AC setup to work right. There was an article in the Horseless Carriage mag last year that leads you through getting these type brakes set up to work right. Mine now work well. Also, if you ended up with the batch that used Kevlar linings, contact Larry to get them corrected to the appropriate brake linings. Or do as I did and get the linings from McMaster-Carr.
The article in the H C mag was referenced here recently and has a link on the previous thread.
AC brakes use the small drum so the braking surface is less. I have a set on my '14 and had a bit of trouble setting them up initially but once I got them adjusted correctly they worked fine as a supplement on my light runabout. I think Rocky Mountain brakes stop better as I have them on my other cars but the AC brakes are fine once they are adjusted correctly. It is hard to get the shoes to make full contact with the drum and requires a lot of tinkering but the results are worth the effort. I found that they improved over time as the linings conformed better to the drum.
It would be nice if you could find a way to post that article from HC mag. I don't think they would care. Maybe someone could send me a copy of the article in a PM. Thank you.
