Brake pad replacement - does anyone do it? How? Why?(8 posts)

Brake pad replacement - does anyone do it? How? Why?PdxMark
Mar 7, 2003 4:44 AM
Having just wrestled replacement brake pads into the "shoes" that the pads supposedly slide into, I wondered whether anyone else does it and if there are any tricks. Or does everyone do it just once and forever after buy one-piece brake pads with integral mounting posts.

I finally got the pads in the shoes with the help of a bench vise, which I alternately used to (1) grip/smash the pads as I shoved the shoe along the pad and (2) smoosh the pads directly into the shoe. I doubt either was the recommended Park Tool method...

I replace my Dura Ace pads every 6 months or so. My rims chew them up faster than normal (Zipps).

I put the bike in the stand and remove the wheels. I remove the screw at the rear of the brake pad and push fron the front with a flat head screw driver.

I always clean the shoe (or whatever it's called) before installing the new pad. Brake just and debris collects in there and may make it harder to slide the new pad in.

Nothing wrong with using a bench vise but you probably could have found another way that didn't require you to remove the shoes from the caliper. What's nice about the inserts is that you don't have to realign the brakes to the rim. Just slide in a new pad and use the barrel adjuster to get the appropriate offset.
Thanks. It was the just slide in part that was getting me :)nmPdxMark

Cleaning tip: toothbrush / Insertion tip: hairsprayBergMann

That first post was right on the money -- your problem was undoubtedly dirty brake shoes. Particularly on my XTR V-brakes (which see a lot more crud than my road brakes) I like to spray a bit of alcohol on a toothbrush and scrub the debris right on out of the grooves in the aluminum shoe.

If you're still having insertion difficulties (i.e. due to aftermarket pads), try spraying just enough hairspray into the shoe to get things moist and then slide the pads in quickly before it dries. This is an old trick shop mechanics use e.g. to get rubber MTB grips onto bars. Wet hairspray serves as a lube, and when it "sets" as a light adhesive.

Whatever you do, hold onto those shoe/insert combos! There is nothing more annoying and frivolous than re-aligning perfectly adjusted brakes, just because the pads have worn down!

You have Dura-Ace. I believe the original poster has Campy. That could be the difference -- I've never had any trouble changing pads on my Dura-Ace brakes. By the way, if you've been using Dura-Ace pads, I recommend you try Kool Stop. I switched from Dura-Ace to Kool Stop pads; my braking performance improved dramatically, and the pads no longer chewed up my rims.

Keep in mind I'm using Zipp rims. Dura Ace wear faster than normal. I tried Kool-stop pads and didn't like them. They make more noise on my rims and wear even faster than DA.

Kool-stop pads didn't work for my situation but I'd expect different results on an Aluminum rim.

Put the pads in the fridge for a few minutes (like 30) so they shrink a little and harden a little too. Helps them slide right in from my expirience.

i'v replaced them..they slide right in..loosen the skrews lol-nmbenja15
