Brakes :: Free brake check
"Lifetime guarantee
To ensure your brakes are always at their best, we offer a unique brakes lifetime guarantee. Once you have pads or shoes fitted at Kwik Fit, the replacement of these parts when they wear out is absolutely free to you, as long as you own the car."
Sounds like a deal to me, may try them once I need new pads although at 8500 miles so far they seem fine.
