I have Power Stop Z26 rotors and pads, so will these monster or oversize calipers work with the backing plate from Scare bird?

GTO F product code is what I’d like.
MST Monster caliper kit, too.

We usually recommend soft organic pads for how most drive these vehicles.


Yes on the calipers, they were made SPECIFICALLY for GM apps

Both calipers offer 21% more pressure. Is the main difference to two and three-quarter inch piston in the monster caliper? Let me know about that and I’ll be ready to place an order later this morning. Let me know which p/n I Need to order if I missed something.

yes, they are new castings using the Mopar 2-3/4" piston - a better match for GM masters.

OK I placed an order with the monster caliper and the other parts of the brake kit. Let me know if I missed anything for this to replace my factory power disc brakes, ok?

[Scarebird]

Thanks, I will.

Thank you Scarebird!

Kudos to Scarebird! My monster caliper shipped about eight days earlier than originally told. Five days from order to ship pretty good when he said two weeks to begin with. Now I have a whole bunch of power stop Z 26 extreme brake parts coming in. Rotors pads rear drums and shoes plus the monster calipers, it should be a stopping force of nature! I’ll post some pictures once it’s all done. Thanks again Scarebird!

Well, the kit didn't fit my factory power disc brakes. The backing plate didn't have the proper spacers, or didn't provide for the indent needed to mount flush to the spindle.

The backing plate needed to be filed to fit the Monster calipers that were sent by Scarebird.. I tried to resolve this for two weeks, multiple emails, pictures of the spindle, plate, etc plus the casting #'s of what I had on the car.

Of many replies, a few stood out...

Your mechanic doesn't know how to measure the caliper piston (that turned out to be incorrect).

Six pictures and several emails later...
You either have power disc brake spindles or drum spindles that have been cut down.

Two more emails and more pics of the specific GM casting #'s, pictures of the power disc brake spindle front, back, center and damned near upside down and the reply was:

Our stuff doesn't work with your spindles.

I sent the kit back on my dime. Scarebird receives it and has to file on their own backing plate to make it fit their caliper, ignoring the fact that it wasn't the right plate for the spindle to begin with, and declares that this shouldn't be an issue, and implies that it's not his fault. I dunno, usually when stuff needs to be modified to work, that should be in the instructions...right?

Uh, right....

Then the refund for the wrong parts was minus the shipping because their QC didn't catch the plate filing/fitment issues, and apparently two caliper bolts were missing...my bad on that one.

So, I get a refund minus $48 from $360, plus the return shipping I paid for, two weeks of aggravation, my mechanic's time to try to figure out why all this isn't matching up, and Scarebird's repeated denials of having done anything wrong.

I imagine by the time I pay my mechanic to diagnose the shortcoming of the Scarebird MST caliper and matching plate, I'll probably have lost a little more than what I spent (over $400 I figure)...well, plus ordering a whole new Wildwood disc brake setup that I'll get in four weeks.

The shop put my factory power disc brakes/rotors/etc back on, and I can pickup the car tomorrow.

Not the experience I had hoped for, and certainly not what I paid for. Buyer beware!

Hi Jim, you did not do ANY of this work, did you?

You did not mention that we got the parts back, test fit them and they fit fine.

We did not "file down the backing plate", we spent 10 seconds on the caliper with a file and it slid in (machining burr)

Here is a pic of it test fitted:



This is how his "mechanic" measured the piston of the caliper:



Why yes, the anvils of the dial caliper are INSIDE the piston...

We did offer to build a set of brackets that would fit the disc spindle but Jim decided against it.

We refunded his money minus shipping and for parts not sent back.

Needless to say we regret ever having anything to do with this guy.
