Ok..I just found out the tool I have and what most kits have is too big to fit our small pistons. The spacing between the pegs is to great.
I found the right adaptor to fit here:

Schley Products, Inc , 67380 3/8 In Dr Brake Caliper Tool Adapter - Mazda Mini Volvo

•This new 3/8” brake caliper adapter has been specially designed to work with other brake caliper tools available on the market.
•This new adapter can be used for Mazda, BMW, Mini Cooper & Volvo vehicles.
•These vehicles have smaller brake pistons than other vehicles.
•In operation, the tool makes clearance for new, thicker brake pads by rotating the brake piston back into the caliper until the piston is bottomed.
•Rotating the piston is required on most disc brake calipers which are also used as emergency brakes

 

good find...

 

I'd rather spend another $25 and get the one that braces against the opposite side of the caliper. You'll see. Sometimes the piston twists right in. Sometimes you need to eat your wheaties, or use a better tool

 

nice, autozone has one for 10$ universal worked great on mine.

 

go to Autozone and they let you borrow their Caliper Tool. you have to put down a deposit though.

 

The autozone kit will work but none of the adapters fit just right, this tool fits perfectly in our pistons.

 

my needle nose pliers worked great as well!!!! haha really...

 

Are you talking about the Schley tool I posted or the other *big* kit?
If it is the Schley..have you actually used it?

 

I'm talking about the autozone rental kit, none of the adapters quite fit our pistons. I haven't used the tool you posted, was just trying to reiterate what you said in the op

 

OK..well that one WILL work. BTW...This is Volvo S40 Caliper..exact same one we have.
Needle nose pliers here!



On a different subject..LUBING PINS?
Here is the same caliper above showing the pin area. NO LUBE and exposed pin (no inner boot ). Do ya think they have our rear rotor/pad problems? NO! It must be the FU$$KN PADS we have!

PIC of Volvo rear caliper and PINS:

 

it works perfectly fine for me. i've already used it twice..

 

I'll take this one 18 Piece Disc Brake Pad and Caliper Service Tool Kit but only because it comes with 17 more pieces and I'm more than likely going to use at least 1 of them.

 

why dont yall stop wasting money and just use the set of needle nose pliers layin in ur garage!! lol

 

You've obviously never done very many of these. Once in a while you run into pistons that will not rotate and compress without a very large amount of force. I've had this happen on Audis, VW, GM, etc. It sucks. Using needle nose pliers is stupid. You risk tearing the boot when you run into a piston that does not want to compress.

 

ahh ok i got ya, iv done em 3times lol but i get wat u mean about the boot and them bein harder than other to compress or rotate

 

Exactly what I said. When it doesn't want to compress, if you're using pliers, they are likely to slip, and you'll probably stab the boot.

Even using the cube thing is no good. What you want is the Harbor Freight kit. The last time I did mine, one of the pistons did not want to compress. Fortunately, I had access to a kit like the HF tool, and got it to compress with that.

 

I did mine with a socket and a couple pieces of thick wire welded to it, definetly not doing it that way again.

 

i cannot get mine to depress. do you have to rotate and compress at same time or can you just pri bar between old pad and caliper like i do on any other car.

 

I'm shocked! Shocked! I've never heard of one of these being hard to compress!

This is why I suggest a real tool which allows you to compress and rotate very easily. Not the crumby cube thing, or pliers (come on).

 

well i kept turning and pressing and the rear passenger side finally depressed with my trusty needle nose. driver side took like 5 sec to depress.
