Place an oil pan under the rear brake caliper. Remove the brake
hose from by unscrewing the 12mm banjo bolt. Some brake fluid will
come out of the brake hose and drip into the pan.
Brake fluid is harmful or fatal if swallowed and harmful if it comes
in contact with skin or eyes. Call your doctor immediately if brake
fluid is swallowed, and induce vomitting. Flush eyes or skin with
water if brake fluid gets in eyes or comes in contact with skin.
