Soft Brake Lever Problem

Purchased a new basic Shimano brake lever for my linear pull v brakes and no matter how tight i set the brake pads i cant seem to make the lever not pull all the way to the handlebar. The wheel cant even spin freely when the lever is disengaged but still when i go to pull it its still very soft. Brake pads are centered as well. I've tried setting the barrel adjuster as tight as possible, then pulling the brake cable as tight as possible, but when i loosen the barrel adjuster slightly so the wheel can spin freely the brake lever quickly gets extremely soft. Could it be a stretchy defective brake cable? Brake pads are pretty much brand new as well

How long is the distance between the lever pivot and where the cable end sits?

Sounds like you have bought a short pull lever. The cable pull is too short, meant for caliper/cantilever/u brakes. Get long pull lever.

Yup, low MA lever wont pull enough cable for high cable pull demands of a V brake

I'm trying to get a 4 finger V brake lever for my V brakes, since a 2 finger is shorter...

longer physical length of the low MA V lever should help my needs..

For flat bars, the Avid Speed Dial Series OR the Tektro (selectable) dual pull levers are the 3rd party replacement brand of choice. They come as OEM parts on a lot of bikes as well. I wouldn't change from Shimano levers if they came OEM but I wouldn't necessarily go out of my way to find some as replacements or upgrades. FWIW.

I might have some lying around. 4 finger is incredibly hard to find. Mine were called that, but in reality 3 fingers is about right. Tektro brand. Seller insists they are the longest levers money can buy. I believe them. But it isn't the lever length. I have some dual pull levers as well. There is a cam mechanism in the lever body that changes the MA. I have some Velo Orange short pull levers and they are some of the longest levers I have. Five fingers and more, easy.

My LBS has a couple vendors supplying these, so shipping is included in price ..Tektro CL530-RS Brake Levers

My MTN disc brake has the Avid Speed dial , it really is not a big difference in it's range, a V lever that can be dialed back a bit..

I have used some levers in repairs , where you put the cable head ,
relative to the distance to the pivot was a set up choice.
