2002 2.7T - ATE FNR-G60 Front Brakes Retaining Spring (Clip) How To Remove/Replace
Searched far and wide for help on removing this pesky retaining spring. You know the one I'm talking about. It's just a wire and it fits under a clip on the outboard brake pad and past two small posts on the caliper to hold the pad in place.
Trying to remove this retaining spring before doing anything else = FAIL
It is IMPOSSIBLE to get this retaining spring out without compressing the piston and removing the caliper pins. So - leave the darn thing alone until you get this done.
Remember to work this retaining spring advice into the more detailed explanations about brake service you can find on this site.
It is much easier to retract the piston in place before taking the caliper pins out. I prefer to clamp the brake line and open the bleeder screw myself - but to each his own. A quick trick is to use 2 stanley wonder bars (pry bars). Put the short curved end of the pry bars under both ends of the caliper, pull back and voila your piston retracts. Retract it as far as you can with the pry bars. Remove the caliper pins (7mm hex). Now it will take you 2 seconds to take the spring out - if it hasn't already fallen out.
You can also compress the piston the rest of the way by hand once you have the caliper off, no C clamp or tool required, just leave the brake bad in place and push on it.
The caliper weighs a ton...so I use a jack stand to set it on and just lean it against the wheel well. Then you don't have to hang it.
When to reinstall the retaining spring you ask?
After you have the new pads and your caliper back in place, BEFORE you put the caliper slide pins back in. Start by putting the retaining spring under the clip on the brake pad and then get both ends where they need to go. There is enough play in the caliper to make this happen. Don't worry about putting the wire past the 2 small posts on the caliper which are there to hold it in place - you will do that later. With the spring under the clip on the brake pad and the spring ends in place - put the caliper pins back in. After you put the caliper slide pins in and pump the brakes to snug everything up - now use a screw driver and pliers to get that darn wire over the 2 small posts and you're finished with the retaining spring (clip).
