new brakes on a KIA

[Norm201]

You learn something new everyday. I've changed brakes in many cars for many years but today was my first encounter with calipers that are of the screw in type. My daughter's 2008 Kia Spectra need need new brakes. The front disc are typical. Using a clamp and an old pad compress the caliper piston. The rears however, are not. I tried like crazy to compress these suckers to no avail. It then dawned on me to call Advance Auto and ask about it. They rented me the tool to screw down the piston. Who knew?

There's a joke in there somewhere... I can smell it...

Something about spending the day screwing with a Spectra...

How about this one:

I wanted to do the rear brakes on my Kia Spectra and I was told I could either go to a mechanic or go screw myself.

I ran into that on an Acura 6-8 years ago. Took me a couple of hours to figure it out by trial and error.

Mazda used them for years... Seems to be a mostly Asian car Co thing.

Maybe they figured you are already screwed for buying a Jap car

VWs also use screw-in caliper pistons.

I was told by the Advance Auto guys that the screw type is the trend in new cars and expect to see more of that type. I don't really understand the advantage or how they work. I can't see how the piston advances as the pad wears. It seems the piston is locked into place by the pad backing plate and the anti rattle shim. How can it turn and extend out as wear takes place?

They utilize the E-brake, err the GM cars of the early to mid 90,s did.
Got me too when i encountered my fist one back then.

This was the tool i used, lost it like 15 years ago.

My 2006 Malibu had screw-in calipers on the rear.

I have seen many many many cars like this where I work and it can be a bit of a pain compared to regular calipers but once you get used to them they are no biggie as long as you have the correct tools for the job.
