Can someone explain how these rear calipers work? I read that you can use a pair of needle nose pliers to turn the pistons in, so new pads can be installed.
I keep turning and it's not moving. What gives? Can someone show an exploded view of these? I don't understand how these work.

Thanks!

 

It's turn AND push at the same time. The pushing compresses the fluid. Try unscrewing the master cyl cap to relieve some pressure.

Needle nose pliers are the plan b if you do not have the correct tool. But it will work

OK> Thanks. Auto Zone has a caliper tool set, I'll try that. If you turn it counter-clockwise, it starts to come out even farther!

 

Yes it clock wise and push in to compress. IIRC. the tool just makes it easier.

Oddly enough my house has no power right now and im answering you plugged into my MINI via a hot spot from my cell phone. Small snow storm took out my neighbor hood it seems. lol. Im bored.

I don't have the tool, but I always used long nose pliers to do it and it works well.

 

I tried to do the rear Calipers without the tool and was unsuccessful.... A trip to Harbo Freight for the kit solved my issue

 

I orders the brake tool set from harbor freight. I didn't even try without it. The correct tool works perfectly and easily! Although I have an R58, there rear brakes seem to be replaced the same.

Needle nose work great for me. I'm all for using the right tool, but only so much room in the toolbox, so if a special tool is useful but not needed, I'll use what's at hand.
Note that I've jury-rigged a belt tension tool, but for me the right tool is worth the space.

 

Push and turn with needle nose pliers actually worked better than the Harbor Freight tool.

 

As calipers get older, they will become harder to turn with pliers.

Get a quality tool (HF may or may not be the ticket) that turns the caliper clockwise at it pushes it it. If you DIY the brakes in your cars, the same inexpensive tool will be needed in all modern BMWs and Audi's, so just do it.

While you are doing your pads, don't forget to bleed the brake fluid if you haven't done so in the past 2-3 years, or are planning to take the car to the track this coming season. There are pressure bleeder tools that make that job easy, get one as well:
