double cable rear brake?
The son of one of my neighbors rides a mongoose BMX bike. He never gets off of it, so I was not surprised when his mom asked me to take a look at his brakes because he was complaining they didn't work.
First problem, there was only 1 brake pad per caliper.
Second problem, the cables and housing had rusted together.
I replaced the cable and housing on the front brake, but the back brake has me mystified. I'm going to give a description below--please pardon my stupidity, as I have never worked on BMX bikes really.
There seem to be two cables in the lever, which travel to different sides of a metal disc around the stem. When the lever is squeezed, this disc is raised. The disc also connects to two other cables, which travel one to each brake arm of a brake shaped like an X with a single pivot.
Where do I find the cables to replace these? how do I service that disc thing?
