This is a puzzle for me and I haven’t had any luck finding a solution on my online searches. It’s like nobody every really has this problem. This is for the emergency brake on a 2008 Toyota Yaris. When you pulled the handle up to lock the e-brake it stays there. The button seems to be locked in and you can’t get the handle to go back down. I have managed to release it only by taking a flathead screwdriver to the base of the handle where there’s this gear (or sprocket) and lifting the part from the gear’s teeth with the flathead and then I can lower the handle.
What I want to do is learn how to repair this permanently. I think it might be the button but is there a tutorial somewhere or someone who can give me a rundown on how to do it?
