Brake lever spring
#1
Hello,

I was trying to put in a new brake wire on a mountain bike Next Px 4.0 24".

Unfortunately I disassembled the brake lever (though it was not required to obviously).

Anyways now that I try to reassemble it, the brake lever spring mechanism is not working. The brake lever is of 'Sun run' brand (Chinese company).

Since I dont have a lot of time on my hand, I am thinking about getting a new brake lever. How do I know if it would fit on the bike's metal handle ?

I am looking to buy a cheap brake lever ? Any suggestions ?

Thanks y'all.

Measure the handlebar diameter. Most brake levers should work, sometimes you need shims, but they should come with the levers. For one of my bikes my LBS had a pair of used Avid break levers lying around that I could have for... dunno... a fiver or so. Just make sure that you get a lever for the style of brkaes you have, V-brakes (linear pull) and Cantilever breaks need different levers!

Thanks for your reply. It says that Px 4.0 has a V-brake installed.

I found this on amazon. http://amzn.com/B001GSMJF4

It doesnt mention for what type of brake system it is for (V or cantilever). Any ideas?

That one will not work; it is "short pull". V-brakes (and most mechanical disc brakes) need "long pull" aka linear.

This one will work:

Hello

Thanks for your reply.

Can V-brakes be visually differentiated from Cantilever ? I am asking this as there is an old mountain bike lying around whose bike lever I could salvage and install on the Next PX 4.0.

How would i know if this product would fit on a 24mm diameter bike metal bar ?

24mm OD is standard for most bars, except drop bars, it will fit. At worst, you'll need a shim.

Thanks a lot to all of you guys for helping out. I was able to succesfully install a new brake lever on the bike. Brake system works great so far !
