Hiya Gavin,
You got some good advice.
Here's another tidbit........your braking system is arguably the single most important system aboard your KG. Whenever you have to replace a part of that system, be ready, willing, and able to replace ALL parts in that system.
Inspect every single component in the system. If you even have a the slightest second thought about any of the braking system parts - replace them.
Always replace "companion" parts in pairs or sets. For example, you are facing the job of replacing the flexible (rubber) brake hose to your "sticky" caliper. Replace ALL four of them.
As my very first boss in the automotive business once said to me,"It's one thing to get a car going; and an entirely different thing to get it stopped."
