Anyone that's done the Lebaron rotor / Cadillac Seville caliper brake swap.... Does your bleeder (or caliper) come close to or hit the lower shock mount on the lower control arm?? I just noticed that with the suspension hanging (car on jackstands) the bleeder screw is buried in the side of my shock when the wheel is turned all the way. If I jack up the suspension to "normal" height, the caliper body crashes into the control arm... I'm guessing this isn't normal??? It's been so long since I've seen the stock Fiero setup (car's been naked for a year..) that I don't remember what stops the steering at the ends. Does the rack just run out of travel, or is there supposed to be a hard stop? The control arms have a little "depression" where it looks like something was designed to bump into them, but I don't know what (or if) that was...

I took some pics, but not sure if I can find a way to get them off the camera. (at a friend's house doing the work..)

I have '84-ish Seville front calipers, and the adapter brackets that were for sale in the Mall a few times over the years. Everything seems to fit fine otherwise, but I know this can't be right.....

I have the same situation on my Lambo that I am building from an 84 Fiero. I do have the Street Dreams 2" drop spindles and wondered if that was the problem. I have the same thing happening as you and need to address it before I get it going on the street. I will be watching this thread to see what comes up.

I've also done the swap, and bleeders did hit the shock. I wound up cutting the nipple off of the bleeder so that instead of something snapping off, it would just rub a little at the extremes of turning.

The caliper bracket that used to hold your old calipers had a turn stop built into them, and since they are gone as part of the swap, your caliper's bleeder is going to hit the shock.

I know there are a couple of versions of these front calipers, perhaps one of them doesn't have an inside mounted bleeder?

The calipers i have also have a deep circular pocket that the brake hose mounts in. It forces the brake hose to point in a very specific direction out the back, which seems to stress the hose a little more than I'd like.. I'd have to grind off some of the pocket to turn the hose to a better angle. Another issue with the circular pocket - I have Russel stainless brake hoses (but the rusted crimped ends and fittings are plain bare steel - argh!!) - the banjo ends are square blocks of brass, too big to fit down in the pockets... I had to round off the ends with a grinder. The rear calipers dont seem to have that problem.

I'm not sure that my lebaron brake swap has that issue... maybe my caliper is rotated differently? I'll be changing my brakes and lines out in the next few weeks so I can check for you guys. Thank you

I'm happy to see it's not just me, at least one other person has seen it. The particular caliper I ended up with might be making matters worse though, but I was cheap.. I ended up with Advance Auto's rebuilt brand - Cardone I think. The 2 rears were rebuilt differently (different finishes - one dark, one light), had different e-brake hardware (one looked re-used, one new, one was a torx bolt, one a hex bolt), one had an e-brake spring, the other didn't... I just hope they don't leak! I spent hours cleaning and painting them.. Also one of the front calipers came without 1 set of smaller O-rings; they made me buy a new hardware kit since I couldn't prove I hadn't just lost them.... Riight. At least it was only $5 and it came with better pad clips (which are still a garbage way of attaching pads!) than what came with the calipers.

Since the Fiero brake calipers brackets bolted on from behind and the new caliper adapters bolt on from the front, I'm going to see if I can just mount the Fiero brackets to the back using longer bolts with nuts so they'll act as stops. I ended up having them powder coated with the rest of the suspension, so I might as well get some use out of 'em! I left them at home so I'll have to try next weekend, when I'll also have to replace my stripped outer tie-rods with Rodney's. More parts I should have just bought new in the first place..

Son of a....

I swear I looked through pages and pages of search results and didn't find that thread. I Googled "Fiero front brakes" looking for a good shot and one of the pictures was the Fiero brake bracket cut into pieces. Clicked on it, and brought me to the text version of that thread...... Yeesh.

Looks like another trip to Fastenal. I ordered the M12x1.5x40 bolts for the fronts, went to use them and they were M12x1.75. Brought them back and the guy said he'd never seen them labeled wrong like that before. Figures. We'll see if they can get the right 75mm bolts! Though I really Really REALLY don't want to take the calipers off again..

Excellent find!! I like this idea and the one Will posted in the linked thread.
Thanks for finding this.

I had the same situation with the Russel lines as you mentioned. Click on my 'Home' button, enter site and go to page 7, we had the same solution.

Kevin

Edit to add: I also like BrewCheese's idea on the replacement of the bolts in the link.

Finally ordered the bolts today.. Fastenal is pretty much the only place that seems to have them. $38 shipped, with 4 flange nuts to go with them. I didn't want to drill out the spindles and lose those threads; not sure I trust just nuts to hold that many parts together. Of course I ordered 60mm, and the post in that thread says you'll need 75mm. Hope I didn't measure wrong! 40mm bolts go through the Lebaron brackets, spacers and the spindle with a little to spare, 20mm more should be plenty to go through the stop bracket and pick up a nut on the back. I think.

FWIW, I got (4) 11114841 bolts, and (4) 0162312 nuts. Nuts are only 8.8, but they're really only holding the stops on. If I can break an 8.8 nut just with the steering stops, I'm doing something very wrong and probably won't survive it.
