Buick Encore Brakes to Sonic

[MPFab]

ok... the brackets mpfab used are the rs ones though, right? He has a non rs that he put them on though I do believe correct? Why couldn't someone swap drums on a non rs to the sonic rs rear disc parts then. I know that the "axle" in the back is a different part number from rs to non for some reason and I though it had something to do with the fact it has rear disc.

That is what I am doing. Rear axle is exactly the same. Drum parts will come off, and these, along with calipers and rotors, will go on.

so its as simple as that? thats what ive had in my head this whole time

 

[CheapFuneral]

I wonder if anyone on here also has a encore, diesel cruze or trax?

I do.


**** you auto correct!

So is the encore 5x105? I could check this this weekend, I've been wanting to see my car with the encore wheels on it, just haven't tried...


**** you auto correct!

yes!

Btw,
Encore rear calipers are the same P# as Sonic RS calipers. The rear discs from the Encore should work as well. The overall diam. and bolt circle is the same, however, they are slightly thicker by 0.03(0.47"Sonic RS vs. 0.50"Buick Encore.
Reason I mention this is I just scored a MINT pair of rear Encore calipers with less than 5K on them for $139 SHIPPED!! Getting closer to brake dust on my rear wheels...wait...whut?

This is actually fantastic information. I've been pretty weary on getting the ZZP rear disc kit and would like to use parts that were originally made for the car as much as possible. Gotta have that sleeper status.

So i snapped some picks at work today of the front rotors for the encore and sonic to compare.

The size difference.

Bolt spacing. I stacked the rotors and alligned the holes, perfect match 5x105.

And the height.

I have quite a few more pics but I figured if anyone asked for anything more i will post them then. Also the part number on the rotors (encore) are 48881025 from Napa.

CjCsonic, you da MAN! So the Encore rotors don't need to be redrilled and are the size we want? That plus the Encore caliper brackets = big brakes for Sonic.

Well..... At this point in time I'm going to say... Absolutely!!!!
I have my new bracket coming in the next week or so, once I get em in it'll be a day or so until I get everything installed and will then repost some pics. :banana:

Also I forgot to mention. The brake pads from the sonic and encore are technically the same.

I only had the pictures to reference for the encore pads but the only difference I see is that the sonic pads are chamfered and the encore pads are not. Unfortunately I do not have the encore pads in stock and I am not paying for shipping them in.

This pic isn't the best but it's what I could do to show a comparison.

Are the Encore pads on the left? do you think they would be a little taller(?) to make use of the added diameter of the rotor? Otherwise there will be an unused part of the disc about an inch in height right by the rotor hub since we'll be positioning the calipers further from the center.

BTW, I just ordered a set of Encore rotors.

Edit: the Encore pads do appear to be taller, looks like I be picking up pads too.

Doh! Snooze you looze!

Lol I knew it, oh well....

Also the pads on the left are the encore and right is sonic. I would not think that there is any difference in the height of the pad material.

I see what your talking about now. Idk for sure, it appears it is taller/longer, it might be the picture. I'll double check tomorrow at work and look at the pics again. I might be ordering the pads and eating the freight to be sure.....

 

[Stew]

Not the thickness of the friction material, the overall height dimension of the pad. Look at the Sonic pads, the edge that is closest to the rotor's hub has a more pronounced curve than the Encore pads.

Not a big deal, the Sonic pads will work but they won't utilize the whole disc.

I just ordered the brackets. Also, FWIW the Cruze diesel caliper brackets have the same part number as the Encore pieces according to newgmparts.com
