How is the LBS gonna fix it....(9 posts)

How is the LBS gonna fix it....t-moore

I have a LeMond Nevada City Bike with the generic brake calipers. The alignment of the brake pads is off on both of the calipers.

I have tried to twist and bend to straighten the brake pads to no avail. I know that hardest part of most repairs, is putting your hands on the proper tool.

How is the LBS going to get the proper alignment and toe in of the brake pads.....

They are going to wait until you leave the shop and then take the wheel out and use a pair of vice grips to bend the calipers in or out.
Just take the brake shoes off the calipers and grab onto the flat part that the shoes bolt onto. Try to do it in 3 or 4 moves so the you don't bend them more than needed. After the first bend, put the shoes and the wheel back on to see how you have done.... Repeat as much as needed.

It's not actually vice grips, but Park makes a tool specifically for this. It is basically a long chunk of metal with slot on one end and a handle on the other. You just slide the slot over the brake caliper arm and bend away. The cheap brake calipers that come on that bike are pretty soft aluminum and not too high grade, hence their malleability. Just bend to the proper toe, and your done.
The tool is the Park BT-3, and here's the info from the website...

What about that poor little bolt...KeeponTrekkin

that attaches the caliper to the fork/frame (whose proper name I don't know)? Do you "realign" both caliper arms at the same time so you don't bend that little bolt?

Not sure I follow.. you mean the bolt that attaches the brake to the frame in the rear, and goes thru the fork up front? That is a steel bolt, it shouldn't bend. The caliper arms are all you need to bend. They are aluminum and pretty soft at that. You just gently pull them into toe with regards to the pad and the rim. If I am missing your question, sorry, but I didn't really follow...

I appreciate all the chatter on the subject. I think I will buy that Park tool and take care of it myself.

Why we are talking about brakes....Anyone familiar with the Aztec formula 1 brake pads that are RED in color..

Use a 10" adjustable(crescent) wrench. The jaws are thicker so there is less chance of marring the surface.
