Should I convert front brake from rim to disc?

I have a 1999 Schwinn Moab that has rim brakes. The front suspension fork has mounting holes for a disc brake caliper. I like the bike and am not in the market for a new MTB (yet). Is it worth it to upgrade the front to disc brakes? I have never had an issue with the current rim brakes, but I feel the new technology is the way to go.

I found a Shimano, hydraulic front brake package (caliper, rotor, lever, hose) for a great price. All I would need is a new wheel and mounting adapter.

Does anyone know anything about this model?:

If you want to upgrade, why not? Go for it.

If it's not broke don't fix it, as the saying goes. If you have no complaints now there would be no reason to replace them.

I'd save my money for a more current frame that has disc mounts as well, then upgrade

Overpowering your front end brake vs your rear rim brake may not be a good idea. Especially since as you said "I have never had an issue with the current rim brakes". If you had the ability to change both front and rear I would say sure go for it, or maybe just the rear, but not just the front.

Why not just the front? Most of your braking comes from the front, so it makes sense to have a stronger brake up front. It is common to see mountainbikes with a larger rotor up front.
And front disc, rear v-brake was pretty popular back in the day.

I would go to a cable disc. A good one like an Avid BB7. I bought a set for my '98 cannondale.

I hate bleeding brakes and maintenance on my motorcycle brakes and all I thought was why the hell would I want to add another thing that like that.


does you hub in the front have a rotor mounting surface? check ebay for a cheap disc wheel but its somewhat more difficult to find them with the small 9mm axle vs. the 15mm axle of more modern forks.

I would not do that.....

It would not be wise at all IMO because wheels need to be built stronger for disk brakes, Rim brakes to not put pressure into the spokes.
Disk brakes apply a greater force by design at the hub to stop the wheels momentum....

~IF you are riding hard enough to justify disk brakes then you will benefit most from hydraulic brakes. 'Wet' brakes are ten times more powerful than cable disk brakes adding more pressure to the center of the wheel.

If you want disk brakes for their far far better performance In wet and or muddy conditions then Hydraulic disk brakes are Indescribably more powerful and offer an extreme amount of control above cable disk brakes.

I added the very good Mechanical Avid BB7 to my recumbent rear wheel and had very good results. I needed much more stopping power than the rim brake could offer me. BTW the rear wheel was already built for a disk brake.
My Tour Easy is very rear wheel weight biased and the back brakes does 70-80% of the braking due to bike design. I did not need Hydraulic because I do not ride at the edge of the bikes performance envelope nor do I ride in the rain.. My mountain bike,,,I ride very hard...

If you are riding true single track and need that kind of braking performance then you would benefit even more with a modern mountain bike with modern geometry... 1999 model,, a nice flat trail and fire road bike, a keeper I assume...

Deore hydraulics are good; almost as good as Deore XT but cheaper. They don't have the "ice-tech" features of XTs, but those are mostly heat-ablation features that a recreational rider won't ever need.

I swapped out the cantilever brakes on my '04 Cannondale F500 because:
I found a disc wheelset locally for $50 (needed some truing and I overhauled the hubs)
I had a set of Tektro Gemini hydraulics sitting around (upgraded my fat bike to XT brakes)

My Cannondale had disc mounts front and rear, so it was an easy change, and a huge upgrade in braking. Dangerous, because you can easily do a forward endo if you grab all the front brake. But they're easily modulated once you learn to be more careful.

I'm totally sold on disc brakes (more effective than rim brakes, IMO), and totally sold on hydraulics (more effective than mechanical discs).

FYI, you can get any Shimano parts for super cheap from Germany. That's where I got my XT setup. They don't carry the older Shimano 447s you posted (and it looks Jenson only has the front), but they have newer Deore 615s for $90 (set) and XT 785s for $127 (set).

I was assuming it was more of an upgrade the bike to upgrade it compared to a need of performance which is why I added the cable brake comment. I agree that if you need hyd brake stopping power you really would be exceeding the the capability of the fork and the bike in general
