Integrated Parking Brakes?

Hi everyone, I'm new to this forum and new to the whole Chevy family!
I bought a, new to me, 2010 Impala LT 3.5L and so far I absolutely love it.


I'm looking to do the brake pads and rotors and looking online for some parts. However I've run into a wall, where it's asking me if my vehicle has integrated parking brakes? I'm not familiar with what this is and how I should go about searching to see if my car is equipped with it.


I've called my local Chevy dealers and gave them my VIN, however they have all said they can't tell and I would have to search for it with out telling me what to look for..


Thanks in advance!

I believe they are referring to how the parking brake is actuated. Some have what is called a "top hat" which is a set of small brake shoes inside the rear rotor. The rear rotors resemble a top hat hence the reference. The raised hat portion has a small brake drum cast into it. The integrated type are actuated by an arm mounted on the rear caliper.
A special tool is required to wind the piston back into the caliper, whereas the top hat type piston can be pressed back in.

You can rent or borrow the tool for winding the piston back in from an auto supply store I'm pretty sure. Some guys have success using needle nosed pliers, however the tool will have it done in a fraction of the time.
If you have a look behind a rear wheel and see a lever on the caliper you can tell your parts supplier what you have.
Lever operated E brake or Top Hat type
HTH.

Welcome to the forum as well.

Some things are better left unsaid, which I generally realize right after I have said them.

My '10 Fleet LT had normal rear calipers, and I just c-clamped the pistons open as I did the fronts, the E-brakes never came into play during the job.

I never thought there would be a difference in rear brakes for a 2010 civilian Impala.

There was a change from the "top hat" type to the lever operated ones. Not sure why or when they did it but (it's on here somewhere ).
Top hat type brake job is so much easier to do.

apparently my 2010 LS "GM executive vehicle" has the integrated as i've never messed with the parking brake on the rear through two or three pad/rotor changes. and they've always "just worked."

The only car I have with the new style rear parking brake is my 2007 Pontiac G6 (Epsilon ~1.5 platform). The first (and only) time I did the rear brakes on it, it was a royal PITA. But that's mostly 'cause I had to figure out how to crank the piston back into the caliper.

But reflecting back on it, now knowing what I learned, it may not be so hard. Now owning the cranking tool (the little cube doololly) getting the piston back in may be easier than using a C-clamp on a hydraulic setup - certainly no harder. And adjusting the parking brake is surely easier than with the tophat style shoe setup. I can't count the cuss words I uttered working on my son's 02 Impala parking brakes recently

Of course, next time I do the new style, I could find myself coming back here to retract this

So you have the top hat style on your 2010 then ?

Must have been after then that they changed to the Lever type

Well im not sure. The rotor was a normal looking rotor with no additional pads on the inside of it. I believe the parking brake is done by the caliper itself. Ive never even adjusted it either at 150k almost.

You say you put new pads on so I must assume you wound the piston back somehow

Oh sorry, correct. Yes I've pressed in the caliper before. I think the rears were not a screw style yet ( i gently start pressing the caliper back in and if it moves i know im good or if it doesn't move i know its a screw style). Haven't done it in 2 summers, my memory is a bit fuzzy.

if you pressed them back then there is a small set of brake shoes under the caliper, if there is a lever on the back of the caliper then you had to screw them back in.
Pressing in the "screw in type" will damage the parking brake mechanism.

I'm sure it will all come back to you next time you mess with them.

So, if it's a "hat", my car should have integrated parking brakes? I mean, the caliper is there so it's a combination of drum and disk brake?

I ordered a rotor and pad on amazon and they sent me the integrated parking kit and what they sent me was completely different, sizing is off and the pad was wrong.

PS: Admin, I tried to upload some photos, drag and drop and the attach file button but it keeps giving me an error.

Actually I believe the caliper with the lever on it is of the "integrated" type.

Pauly's right. The lever is on the caliper on the new type. Yours had the hat, so it's the old style with the parking shoe inside the hat.

(BTW, There is also a lever in this system, but it's near the bottom backside of the vacuum plate.)

Yeah, you definitely bought the wrong rotors if you bought those that are pictured....
