The brake booster was from user: Desert Sasqwatch
The master cylinder was from RockAuto...

unsure if I could specify which year and trim, many assumptions were made on my part.
I'll be putting them both in the classifieds once I do confirm which trim they are.

I am facing choosing a master cylinder for my creature. I have 2 different calipers sourced from Cobalts, 2.00” and 2.44”. Obviously my master cylinder choice must support them. Any suggestions/help could only bring me closer to a decision.
I despise doing research already done by others!

Sorry, make that 2 different sized caliper pairs, 2.00" Rear and 2.44" Front. The 2" uses a smaller brake pad, but on the same size disc.

BTW, DS tried to send me home with that same booster!, I'm glad it has found a good home. A real case of what goes around. I gave him a tub of wiring, switches, a BCM, gas pedal and other HHR leftovers when I visited his lair. (he likes to experiment.)

paired with a [Raybestos MC391187 Professional Grade Brake Master Cylinder] from Amazon that was categorized to fit a 2010.

I am pretty sure at this point it was a mismatch on the dimensions as well as the engagement point between the two...

So you are stating this combo does or does not work?

What calipers are you using and what are their piston bores?(roughly)

this combination did not work for me. uncertain what the piston bore sizes were... rear are from donor and the front are from DF...
I think the problem was isolated to the bad combination of the booster and master cylinder not matching exactly.


the latest development is in the aesthetics department...
the engine cover is getting the sticker bomb treatment and it is slowly coming together.
the driver side panel is nearly covered and will get a bit of heat shielding to boot before applying a clear coat to hold all the scraps together.

The Side panels are getting another iteration beyond the failed previous attempt to try and get a single sheet of thick Lexan to bolt up to the frame with threaded inserts.

I appreciate your report on the particular pitfalls you encountered! I can determine caliper bores from your descriptions.
Oh! And I’ll add on some particularly Aussie stickers for your Goblin! My daughter's car is getting quite a few too! We are in Port Douglas on the Great Barrier Reef just now. I’ll mail them when we return in Dec.
