Can someone tell me which Kool Stop pad to choose for my 88 Miata 615 . Here's a photo of the original pad which is 53 mm long. Thanks

If you go to the kool stop site and click on "products," you will notice two options: unthreaded posts with pads (like the City and Eagle2) and unthreaded posts with holders (shoes) for pads.

Getting the holders will make it far less expensive to replace the pads later.

I would check ebay. There might be a non-kool stop holder out there that's less expensive than a kool stop offering but still allows you to mount kool stop replacements in the shoe.

Also search for used cantilever brakes on ebay with the holders attached. This might save you money. True story.

What ever post mount cantilever pads will work, but if you don't have much clearance between the rim and the fork, you might want to avoid the extra long MTB ones, and if you don't have barrel adjusters for the brakes. There's less advantage to cartridge pad style holders for post mount brakes, especially if you don't have barrel adjusters and might be adjusting for brake wear by actually moving the post.

So either city or eagle 2 should work?+

Most likely. The Eagle2 is a pretty big pad. There is a possibility it could brush against the fork or stays. If it fits, it's a great solution due to its size. You might want to order a single pair and fit it for size on both front and rear before you commit to two pair. If the bike is operable, you could ride to your shop and check it through the packaging. These are popular pads, usually held in stock at bike shops.

I think they would fit. The front pads have about 1/4-1/2 inch gap between them and the front fork with the original pads.

(Copypasting from my reply on the other thread...)

Those pads look fine. Start with adjusting the canti brakes as suggested in the other thread. But if you do decide to replace the brake pads, I'll recommend two that have worked well for me:

Kool Stop Eagle 2 (formerly Eagle Claw and sometimes still advertised that way). Outstanding pads, and easy to set up for toe-in to prevent squealing. I've use those on my Univega's canti brakes for about 3 years.

Unfortunately the thick Eagle 2 pads didn't permit enough clearance on the fork to drop the front tire. So I switched the front to Jagwire thinline, long, curved pads. Also excellent and inexpensive. The black pad material brakes as well as the salmon Kool Stops. Only tricky bit is the toe-in. I use zip ties to set the spacing for toe-in. After a little practice it was easy. I think Jagwire calls these pads their Mountain Sport Canti 70mm pads. They're longer than usual for more braking surface, curved to match the rims so there's no risk of the longer pads rubbing the tires, and thin enough to clear any wheel/fork.
