Kona Caldera Issue with Vbrakes and Diskbrakes rims.. Help..!?

Question

I currently own a 98' Kona Caldera, which is the best bike I have ever riden, so I do not wanna trash it, lol!

So I know its a mountain bike, but because I am a smart one, I took a dirt jump and I bent the rear rim badly! So after finaly getting a replacement rim, its not that great! Heres the deal, the only rim we could get (1.95-8gear) was a V-brake plus Disk-Brake rim! So I have the V-brake groove on the rim PLUS the little Disk-brake holder piece. Now I cannot put rear disk brakes, i dont have the right piece on my frame!

So my problem is that I need to know how to ajust my brakes correctly with this type of rim. With my old rim, it was extremely easy, but with this new one its really a hastle! Please the sooner i can get an answer the best. Thanks you

Hey Cansat,

I am a little confused about the replacement rim you had purchased for your Caldera.  You mentioned a V-brake groove and a "Little Disk-brake holder".   I think the V-brake groove is the sidewall braking surface of the rim, but I am not sure what the "little Disk-brake holder" piece you are talking about.

I understand you cannot mount rear disc brakes, because your 98 Kona Caldera did not come with rear disc brake tabs or mounts to install rear brake calipers to the frame.

Anyway, from the information you gave I think you might have the wrong rim.  You might have a disc brake specific rim, so your v-brake pads are not setting up correctly.  I know you said, you had a V-brake plus Disk-Brake rim, but could you specify the brand and model name of the rear replacement rim?   Thanks

*Edit: It sounds to me that your rear rim is out of dish, meaning who ever built the rim for you did not center the rim correctly with the hub or you have a defective machine built rear wheel.  Even though a rim is built with a disc hub or a non disc hub the rim should always be true and centered when correctly mounted in the rear drop outs, so the end user can use either a Disc brake (with disc hubs) or a rim brake if the rim is compatible for rim brakes like your rims.  

You might bring the rim back to where you purchased it and have one of the bike mechanics comfirm that the rim is true and not out of dish.  Something does not sound right with your new rear rim.  Good luck and let me know what you find out. = )

Hi,

Well If I'm Correct If All Brake System Is Still On The Frame That Was On Before And The Disc (Rotor) Has Not Been Changed There Shouldn't Be Much Of A Problem. I Need To Know What Brake We Are Looking At Before I Tell You How To Sort It.
