Ok,I don’t know why I search web when I can ask the B/F Mechanics.So I Apologize.Oh I’m visual.Anyways,just received my Kool-Stop pads i can’t remove old pads.I’ve had them in freezer per someone advice hasn’t worked any other ways?
Thank You. oh brakes are 999 Weinmanns

Elaborate on "can't". What is (or is not) happening?

Lots of folks here are visual. So can you post a pic or two?

(BTW, your old brakes, being in the freezer, are now kool stops as well.....)

Try putting some lube on the pad holder and let it seep in. Otherwise it takes a fair bit of pushing and juggling with rod like tools to get then to let go.

I see what you did there

Thar you go, koolkat~~

I will assume these are pre CPSC holders with one open end.
I just faced this with a pair of Weinmann holders and a pair of Campagnolo.

the old material can get very hard and a challenge.
what I ended up doing to have a predictable process was take a short section of angle iron
drill a 6 mm hole as close as possible to still turn a nut- mount the holder to that- set it in a vise and knock the pad out with a drift and hammer. Took way more force than it did as a mechanic 45 years ago- but success.

pushing the new pads in is much easier- using that same vise.

When I changed over to Koolstops, I just used the Shimano type pad holders. Easy pad changes, with a simple screw, concave washer gives easy toe in adjustment, and I find the thinner pad easier to adjust vertically, and it makes them interchangeable with my other modern bikes. They stop great too.


Works great for Universals too.

Not enough info. Is it one of these 3 types?

In the freezer huh? In most cases if something is really stuck, heat works better.

The old school way to remove them was as follows. Try this first. Take the pads off the brakes. Squeeze the rubber pads only with a vise, knock off the metal holder with a big ass screwdriver or equivalent and a hammer. If they're still stuck saw down the middle of the rubber down to the holder. Try not to hit it. Then put them back in the vise and try again.

I've recently done this on my 1984 Fuji, probably original pads. These are studded holders so I did not have threads to protect. Clamped the holder in the vice, stud between the jaws, and rolled the old rubber out grabbing it with "channellock" pliers. I then warmed the new "weinnman X" pads in hot soapy water and rolled them in. For assurance I then unclamped the stud, slid it down into a long socket from my socket set and put that back in the vice. Squeezed the whole thing a bit to ensure the new pads were seated in the holder.

On another project with threaded four sided holders, I broke off one of the end tabs and slid the new Koop stops in. I'm clever enough to orient the holders correctly when I install them on the bike. I do paint the open end silver in case I'm spotted by a CPSC officer. No hard time for violating Federal regs.

Center one

For that kind, same as before. Grab the rubber pad with the jaws of a vise, jam a screwdriver between the rubber and the holder to wedge it up slightly, then use another punch etc to tap off the metal holder by hitting it on the edge.

good image the center one was effort way back even. The closed one on the right was post CPSC and the success in opening up the end was variable. Most of the time we just fitted new assemblies. Today, I would open, remove the pad then cut the tab off. Chances of successful bending back are not good without cracking.

Or just use a modern holder as described above.

Salamandrine 

Yeah, I think I tried that once. Not worth the effort. There's was always at least one full display card of brake pad assemblies hanging in the shop, and usually that's what went on bikes in for repair. It wasn't usually worth the the time to replace rubber only. We only did that with Campy brakes and the like.

Worst case, just drill it lengthwise and use a saw or utility knife to split it down the middle
