Brakes

Ok, I've at last decided on what style frame I want, and what tyres, and what forks... basically everything apart from the most important part of the bike, the brakes.

Basically I was wondering if anyone could give me a quick rundown of the different types of brakes and what their advantages and disadvanteges are.

Also when I was looking at bikes I took one out for a ride with double pivot thingys and they hardly stopped me at all. The guy in the shop said it was because of a waxy layer they put on the brake pads when new. Is this true or was he just trying to sell me the bike?

Bikes: Catrike 559 I own some others but they don't get ridden very much.

The rest of the bike often determines what brakes will work.

Dual pivot road bike brakes won't clear tires that are wider than about 28mm.
Disc brakes, cantys, and linear pull brakes have to have fittings that are welded to the frame.

Brake pads do make a difference but if double pivot brakes weren't stopping to your satisfaction, I'm thinking there was probably some kind of set up problem.

I have never had a waxy layer. There might be a little laminate like feel on them, but they do not seem to diminish any stopping power.

Dual pivots are road bike brakes and if you compare them to other, nicely adjusted brakes, they feel useless, but in practice they work well enough. Unless you are used to road biking or are going to be used to it, dual pivot or some single pivots such as Campy or older style stuff will feel very scary. Road racers use dual pivots, granted they cost hundreds of dollars per caliper, to stop themselves on 50+mph descents so they are good enough.

The brakes on the bike I tried in shop we're useless tbh. I could squeeze both front and back till my knuckles were white and it would take me a good 500m to stop from cruising speed. Is it just that they weren't adjusted properly?
