Checking brake lining thickness
You can measure the break pad/lining thick-
ness using a test gauge. Color-coding (green
or red) on the test gauge allows you to deter-
mine whether the brake pad/lining thickness
is still sufficient. The test gauge is in the vehi-
cle document wallet in the glove box.
