How To: Properly Setup and Adjusting Avid BB5 Brakes

13 Adjust Avid BB5 Brakes

Tech TuesdayOne concern that so many women (and guys) have with owning a bike is the basics of fixing it, or how to do basic road side repairs. I do recommend that as an avid cyclist even with some mechanical skills that you should become best buds with your local mechanic (beer or ice cream works well.) I also want women to feel empowered and to have a better idea of what they are talking about. Tech Tuesday is the remedy for common tech questions!

As you know I have beenrocking the Airborne Delta CX bike for this summer going into cyclocross season. Originally I was struggling to adjust the Avid BB5 road calipers that come stock on the cyclocross bike. (Yes, it is a disc brake cyclocross bike.) After several tries at adjusting the brakes as Avid outlines on their website I finally started from scratch using good ole common sense! Once I sorted out my disc brake issues I was getting messaged and questioned about what I did to get them to stop well and not rub!

There are tons of great resources out there showing you the basic ways to adjust the brakes, but they left out key details. Let’s forget about those other instruction and start from the top.

Tools You’ll Need

Tools for Brake Adjustment

Torx wrench, 5mm allen, business card and a computer to read this how to on.

Check brake pads for wear. If your brakes are used at all there is a great chance the pads were worn incorrectly and will never align right. Remedy by sanding or replacing the pads, normally sanding with a fine grit will fix this problem.

Loosen the mounting bolts for the caliper, some bikes have the caliper mount directly to the fork, loosen those bolts. This will allow the caliper to move side to side. Check if your washers are worn or if you can see any grooves out of the normal. If you do, file/sand down or replace.

Loosen brake cable fixing bolt, this will allow the fixed pad to pull all the way out.

Turn the adjustable brake pad (red knob with Torx in middle) counter clockwise to turn out.

Business card in Disc brakes

Place a business card between a the fixed pad and rotor. Fixed pad is on the outside (look at diagram above)

Adjust BB5 Torx Brake

Turn the adjustable brade pad (red knob with Torx in middle) clockwise, use a Torx wrench if need be to tighten down as tight as you can with out breaking it!

Tighten the mounting bolts to the caliper.

Pull the brake cable tight to the fixing bolt, make sure the barrel adjuster on the caliper and the barrel on the brake lever both are turned in all the way, then backed out a full turn and a half. Tighten down the fixing bolt on the brake cable.

Back out the adjustable brake pad one or two turns, counter clockwise so  it isn’t touching the rotor. On the back of the Delta I had to back out an extra 1/4 of a turn for out of the saddle movement of the rear end.

Pull out the business card.

Use the adjustable brake pad to change the feel of the brake lever, use the barrel adjusters to adjust cable tension as well.

Check over all bolts and proceed to ride beautiful riding Avid brakes.
