How to Diagnose a Brake Problem

Video Transcript

"Good afternoon. My name's Tom Brintzenhofe and I'm here with you today to help you diagnose brake problems. Usually when you have an issue when it comes to disk brakes for your drum brakes, basically on any kind of brake systems you'll have what they call a pull. Now when you hit the brake petal and it pulls left or right, or you have a vibration when you come to a stop. But we're going to focus today on the pulling aspect of it. Now a real simple way of determining which, which side you have a problem with is if it's pulling left then chances are 90% of the time you're going to have a problem with the right side either not working or being obstructed some how over there. Or with pulling to the right chances are you got a problem with the left because that's the side that's braking and that's why it's going to pull you that way. Now the, the most common problem when you have an issue with either brakes sticking on one side or not working at all is this hose right here. Now when these hoses collapse what happens is you'll push fluid down threw them and it activates this this brake caliper, and it collapses shut then. And this pressure stays out there, so this brake caliper when you're going to down the road is constantly applying pressure. So the easiest way to get them out is just replace this brake hose. Now you got another issue of you're you're brake pads are coming down and held bouncing. That's normally due to this rotor surface not being completely smooth. It actually, if you look at it with a micrometer it'll be a little wavy. So when you put brake, brake pressure on that petal up there and you come to stop what's going to happen is this piston in here is going like this and that's what's giving you you're pulsation coming down threw. And I hope that'll clear up for any kind of diagnostic questions that you have on what goes on with brakes."
