BRAKE INSPECTION HELP
Hello everyone - before i ask the question below are my car details:
a year ago, the brakes started making a slight squealing noise (still present) but below are details:
now my question: 1) how can there be such drastic difference in measurements for these 3 guys 2) how come the toyota guy says that rear thickness when new is 5mm and if thats so how come mineke one gave 10 and 10 written on his service form. 3) what do i do, shld i hold off a brake change or just get it done. 4) what are the actual original pad thicknesses and what thickness should i replace them. |

As an expert Toyota technician I can say that the rear brake shoes start to 4-5mm in thickness. It is possible that mineke didn't even measure your brakes just looked at them and noticed they weren't at the point to be replaced.

BRAKE INSPECTION HELP
Rear shoes don't wear out as fast as fronts because of the breaking ratio (80% front brakes and 20% rear brakes ) furthermore a Yaris is such a light vehicle that it doesn't require much brake force to stop the vehicle and thus your brakes will last longer then most other cars. I currently have a 15 Yaris and previously a 10 sedan. My sedan had 67k miles before I sold it and the front brakes were still at 9mm (this vehicle was an automatic)

just to reconfirm - what you are saying is that the rear break show on the yaris is about 5mm thick (when brand new).... just making sure i understand.

The official numbers from Toyota are 12mm standard thickness and 1mm minimum thickness for the front disc pads with the rear shoes being 4mm standard thickness and 1mm minimum thickness. So if you're at 8mm front and 3mm back than you have plenty of brake life remaining.
The front discs can be inspected just by taking the wheel off but for the rear drums you need to take the brake drum off the hub to inspect the shoe thickness. |
