Can I Upgrade to V-Brakes?

Can I install the new V-Brakes on my old bike?

I have an old (1994) GT RTS-3 (full suspension) Mountain Bike that has the old style center pull brakes (look like short versions of the V-Brake) and would like to upgrade to V-Brakes. Are the mounting bosses (weld-ons) the same for either style? The distance between the mounting screw and the brake pad seem to be the same, I just don't know if the mounting is the same configuration.

I just can't retire this thing, it never got enough mileage put on it to warrant retiring - but the brakes are lacking compared to these "V-Brakes" we have today. So - I'm hoping for the best.
Thanks in advance,
MichiganMarty

You can throw a V right on Canti studs with no problems-But-
First, you'll need new levers for V, second, a well adjusted canti is usually MORE powerful than a V.
It's just that most people don't know how to adjust them.

Yes, but you'll also need to replace your brake levers with V-brake compatible ones.

Normal levers will work just fine with V-brakes if you adjust them. What do you mean by "MORE powerful"? The only thing that determines maximum braking-deceleration is the friction between the front-tyre and the ground. The brakes only need to generate as much friction up to match the friction on the ground up to the point where you lock up the front-tyre. Both cantis and V-brakes can do that just fine. Depending upon the combination of brakes, levers and pads, some may need more lever force than others, but they all can pretty much lock up the front-tyre at will.

I find V-brakes much easier to set up and adjust than cantis. I've switched over a couple of bikes in recent months.

Also, check out the cable routing to your rear brake. You need a cable housing to make the V-brake work. If your bike doesn't have a cable stop at the rear of the top tube you can buy a clamp-on cable stop or you can run cable housing all the way from the brake lever.

Correct. The adjustment involves changing the levers.

Thanks to all for the responses.
Okay - now where do I buy the stuff? I'll need the levers as well as 7-spd shifter for the rear and 3-spd shifter for the front. About all I can find for shifters is the new stuff - 9-spd.

I'd like to get shifters similar to the integrated ones the bike has now - each shifter has a gear indicator and two levers, one to shift up and one to shift down. They are Shimano STX SPECIAL EDITION.

As far as brake levers go, I could care less, as long as they are not ugly and not junk - yet perform.

Thanks in advance,
Marty

Okay! A little work on my part and the last post would not have happened.

I found the:
Shimano STX shifter pods for $26.23 at bikepartsUSA.com
Shimano brake levers LX Deore for $36.99 at bikepartsUSA.com
Shimano Deore XT V-brakes levers for $39.99 each at BikeNashbar.com

Total cost for new brake upgrade was about $144 plus shipping.
This does not include the cost of new cables which I bought at my local bike shop.

Not bad as far as I'm concerned, and it beats going out and spending a whole lot more money for a new bike which is *up-to-date*.

Thanks to everyone for your help,
Marty
