pwmin Posted December 9, 2022 Report Share Posted December 9, 2022 Has anyone done this swap? I know it's not going to gain me much as far as braking power, but I have most of the parts (2G rear knuckles and parking brake assembly, GXP rear rotors and pads) and I'm trying to do all the upgrades Tim had envisioned for this car. I know several people have upgraded the earlier 1G setup to the latter one, but I can't find anything on this swap. The missing link now is the parking brake cable setup. Is it possible to run 2G rear parking brake cables on a 1G? Quote Link to comment Share on other sites More sharing options...
White93z34 Posted December 9, 2022 Report Share Posted December 9, 2022 Someone's probably done it but I'm not aware. Only real advantage I can think of is eliminating the actuator style parking brake or maybe enabling use of GXP style rear brakes. on a 1.5gen it would probably be a relatively bolt on affair given there is no leafspring to worry about. Given how similar the cars are you might be able to use the gen2 rear park brake cables and just join them under the drivers side in front of the rear wheel how factory did, i'm just guessing on that one though Quote Link to comment Share on other sites More sharing options...
pwmin Posted December 9, 2022 Author Report Share Posted December 9, 2022 That's going to be the key: figuring out how to merge the parking brake cables. Bolting the knuckle is going to be fairly easy. I can't use the parking brake right now because of the speaker pods, but I'm going to need to move those and have a working parking brake when it's manual swapped. I replaced all of the cables when I converted my 91 GTP to the newer 1G setup. Quote Link to comment Share on other sites More sharing options...

Raffaelli Posted August 20 Report Share Posted August 20 I’ll be tackling this in a week or so. I’ll probably run no parking brake for a while. GXP rotors/calipers on impala knuckles, mounted in a 94 z34. If I remember correctly, I think I was eyeballing using a N body center console e brake setup to make it work, out of a grand am or something. I forgot the specifics. pwmin 1 Quote Link to comment Share on other sites More sharing options...
pwmin Posted August 21 Author Report Share Posted August 21 I have not done it yet. I was going to do the center console e brake setup. Can't remember if it was A or N body, but I have the thread bookmarked. Raffaelli 1 Quote Link to comment Share on other sites More sharing options...
Schurkey Posted August 23 Report Share Posted August 23 Am I the only one who thinks this is way more trouble than it's worth? I know that the first-gen rear calipers have a bad reputation, but it's not deserved in my (admittedly limited) experience. I know that on my '92 and '93 Luminas, the rear calipers haven't given me excessive trouble--at least, not more than any other calipers, and less than typical aluminum-bodied calipers. I have had them apart for cleaning and inspection; and even replaced them with "rebuilt" calipers in desperation, trying to fix a "hard pedal, poor braking power" situation a long time ago. The poor braking was due to failing vacuum power boosters on both vehicles, not the calipers/rotors/pads in front or in back. pwmin 1 Quote Link to comment Share on other sites More sharing options...
