Correct. The new supplied outlets go up front. The new inner tie rods go out back with the donor outers
Not sure what you wanted to see more zoomed out. Do these help?can you post a pic a bit more zoomed out? I haven’t messed with my rear brakes since the build, but I don’t remember having any issues and looking at pictures, it doesn’t look the same as yours.
Be careful grinding those buttons on the backside of the brake pads as I believe those are the rivets that hold the pad material to the metal backing plate. Having those two separate under heavy braking would not be good. If they didn't fit without grinding maybe your pistons weren't compressed into the caliper all the way?So more progress, but it's a slog. Spent about 6 hours yesterday just getting the rear brakes to fit. Not sure if DF sent me the wrong units or what, but the initial fitup was terrible. First had to file off a significant amount of the bracket ears:

and shave the knuckles ears a little just to get them to play together:

It was like that on both sides. And then the pads DF supplied didn't fit the calipers. The little buttons on the back of both inner and outer pad interfered. I completely removed the the buttons on the outboard pad, but the inboard buttons were needed to fit into the anti-rotation holes in the caliper piston. I had to file about 50% of the buttons away before the pad would fit into the caliper:

These springs were included in the brake kit from DF:

No idea where these go.
Next issue to tackle is why I can't get a firm pedal after bleeding the brakes. This is probably a carryover from the Cobalt, as it had a soft pedal too. I assumed it was a leaky rear caliper, but it wasn't leaking much, and since the Cobalt was donating only the MC, vac chamber and reservoir, I hoped the problem would stay with the Cobalt. No such luck. The Goblin brakes are acting pretty much the same way. I don't see any leaks anywhere - could the MC be leaking into the vac assist housing?
And on a similar, but unrelated note, I installed the DF Dominator headlights and got stuck at the wiring. The headlights have four wires coming out (high beam/low beam/turn/ground), but the wire harness has only three wires. I went back and re-watched the wire harness videos and it appears that Lonny's harness has only three wires too. Is it just a ground wire that needs to be added? Or did the headlight harness skip the turn feature since the mirrors have the turn signals?
Yep, bleeders on top. you can see it in the first picture of post #26Are your bleed nipples on top of the caliper? I don’t see them in the pictures.
When you istall the handle, you might need to adjust the threaded rod on the handle to just take up the slack when the handle is down all the way. If the nut is tighted too much, it will engage the brakes when you don't want them to. Also you might have the piston in the caliper indexed out too much so that it won't retract off the rotor when the hydraulic brakes are released. IF you were playing with the parking brake system without the pads or the rotors installed, the piston may index closer to the rotor as a system designed to account for pad wear over time. with the new rotor and new pads, thay clearance might have been taken up before you used the brakes on the Goblin the first time.After my second shakedown run (about a mile) I pulled into the garage and I could smell the brakes dragging. The rotors were taking on a golden-turning-blue shade from the heat. I'm starting to wonder if DF gave me the wrong pads for the rear too (they sent the wrong pads for the front - discussed in the "This can't be right" thread here on the forum). Detailed in post #24 above, I had to grind away most of the anti-rotation buttons for the pads to even fit in the caliper (the buttons on the pads were 6mm dia and the holes in the caliper are 5mm dia). I googled the part number on the pad (15271565) and it shows its for the 06-09 Solstice. Others on the forum say they're using that pad and it fit without issue. Now I wonder if the pads I got are defective, the caliper piston is defective or if the caliper itself is wrong.
Yeah, that's the tool I used to wind the pistons all the way in. Its how I discovered that the buttons on the pad were bigger than the buttons on the caliper tool.I had to use a brake caliper tool to reset mine to even get the caliper to install on the disc.

Thanks for the suggestion - I backed off the cable tension a little and both wheels freed up nicely!First thing is to check that you have a tiny bit of slack in the cabling at the parking handle when fully lowered
Just wanted to bump this post again to see if anyone has a suggestion for a solution to this problem. Thanks!Another issue that popped up is the function of the taillights. I'm using the DF supplied LED taillights. With the headlights on, the taillights are supposed to have a dim "running light", but they don't - the "running light" is the fully lit brake light. The running lights in the mirrors work correctly. With the headlights on I also have no turn signal or brake lights - the "running light" is on bright, stays bright and doesn't turn off. However, if I turn the headlights off the turn signal and brake lights function correctly (I have the hyper flash, but I can live with that). The turn signals in the mirrors work correctly with the headlights on or off. If someone on the forum has a suggestion to fix the malfuntioning tail lights, that would be most welcome.
Not sure that this can be diagnosed via internet. Going to take a voltmeter and patience plus probably oem wiring diagram. Figure out which wire doesn't have voltage and trace it back. After you confirm you have a good ground for the light.Just wanted to bump this post again to see if anyone has a suggestion for a solution to this problem. Thanks!
