Default Can you collapse the caliper piston on a Passat without the special tool?

I need to change the brake pads on my Passat 2004 TDI. I saw a few videos on how to do this. I have changed many on my FORD truck. All you need is a larger C clamp to do this. Can this be done with simple tools rather than having to find and buy one specifically for that...........now......the reason I ask this is because I have not seen the rear caliper piston closeup as two of my lug nuts one on each rear side have become stripped. Which will be my next post to the forum. Tips on how to correct that. Man the metal on that lug nut is soft.

Any thoughts on if a C clamp or other simple device can be used..? Any support is greatly appreciated. Thank you.

You can get a caliper rewind tool for a free rental at most auto parts stores. You have to screw it back in, you can't just press.

I gather you're talking about the rear disc brakes.

If so, unlike the front disc calipers which *can* simply be compressed with a c-clamp etc, the rear brake calipers need to be rotated as they are compressed, due to the emergency brake mechanism only found on the rear brakes.

There's a special tool your can buy/rent... you can also turn 'em with waterpump pliers if you're slow and careful. If you don't rotate 'em while compressing you'll ruin the caliper unfortunately.

I use a C-clamp on the front.........presses in with no issues. About two weeks ago, I did the front pads on my brother's '02 in about half hour! No reported problems. I have done my '00 Jetta the same way twice on the front and three times on the rear with no issues!

On the rear, I've used a combo of C-clamp and pliers to crank/screw it back in. It's a slow procedure but can be done!

Use a tougue wrench on the lug bolts.

Truthfully, the tool is inexpensive. buy it. But pump pliers will work.

I used to do it with pliers and waterpumps....but the tool saved me a lot of hassle, and three times as fast.

Agreed... plus with pliers you can only retract it so far... and you constantly risk nicking the dust boot.

Pliers are great if you're in a pinch, but IMHO this is one of those wonderful times when you can turn a pain-in-the-butt job into a piece-of-cake job by obtaining the right tool.
