Very effective demonstration. I especially like that you went at a pace that your students can easily follow and gain the concept you intend to teach them. Thanks.
I have similar one and usually change pads when 2-3 mm so no need for rotor service only change the pads most of the time looks good for me I check every 10000 km or once a year
No, that is not correct. However, the groove can be used as a wear indicator by itself because the distance between the backing plate and start of the groove is typically 2mm (indicating the pad is wore out when the groove is gone). Inserting a 2mm red gauge into the groove would actually mean you have at least 4mm of pad left. (2mm groove + 2mm remaining pad after groove is gone). Great question!
@@MrAdkinsAuto He is talking about the square opening in the caliper. Their are many methods of measuring brake lining, even without take the wheel off.
Yes but I suggest changing at 3 mm for trucks new brakes thickness usually 10-12 mm so changing at 2-3 mm means last 1/4 of brake life which considered accepted more will be useless and lower will affect rotor surface so please change at 2-3 mm and you will thank me for that Another advice always change brakes in pairs or as set not one side for example

Thanks. This helps a lot! Now i wont look like an idiot not knowing what im doing

Good job man
Is there a way to do it without taking the wheel off?
Is it possible to use this without taking the wheel off?
Not really. Maybe if the rim has very narrow spokes but it is best to perform the inspection with he wheel off to get a better look.
I thought u put it through the window there and into the groove through the pad lining? That's what I was tought when I got ase certified

@@MrAdkinsAuto and technically those are 9mm. You do have some play.
David Houk in that case you are correct. I thought he was referring to the gas vent in the lining.
Can you use these on heavy duty truck pads?
Yes but I suggest changing at 3 mm for trucks new brakes thickness usually 10-12 mm so changing at 2-3 mm means last 1/4 of brake life which considered accepted more will be useless and lower will affect rotor surface so please change at 2-3 mm and you will thank me for that

Why not just use a ruler?
Drivers should already be familiar with the green, yellow, red system .
