Note the unusual twist of this hose. Previously when the caliper had been removed and reinstalled the caliper had been rotated 180 degrees when reinstalled. This puts a sharp twist into the hose. Note the end of the hose attached to the caliper and how it appears at the right angle bend.
Idea 12Idea 13
When you remove a caliper from a hose attached by a banjo hose fitting use a valve stem to plug the hole. This prevents brake fluid from dripping all over the place and excessive air from entering the brake line.
Idea 13Idea 14
No matter what method of pushing the caliper piston back into the caliper bore you use you should open the bleeder and pinch off the fixable brake hose. This prevents the pushing of any contaminants from the caliper back upstream into the brake system components such as ABS control units, a brake valve or the master cylinder.
Idea 14Idea 15
Even when you simply push the pads backwards to allow their easy removal from a rotor you should open the bleeder and pinch off the line.
Idea 15Idea 16
When pinching off a hose to block fluid flow you should use a properly designed “line lock” type of tool such as the tool shown. Note the tightening is done with a hand turned wing nut, not a hex bolt.
