SquadCarPathfinder Posted February 12, 2017 Share Posted February 12, 2017 So I have researched quite a bit on the forums about converting my 95 pathy drum to rear discs. It's pretty straightforward. The discs would be coming from another 95 pathy. I know that so far for the conversion I would need to also purchase the calipers, brake lines, and maybe new inner axle seals just to be sure it will last a while. I think the whole thing from the local pick your part will cost me a total of about 60-70 dollars. Any tips for someone doing the swap? Link to comment Share on other sites More sharing options...
Cuong Nguyen Posted February 12, 2017 Share Posted February 12, 2017 When I first did the swap, I couldn't remember if swapping out the MC Made a difference. Also do you have lsd or open rear diff? Link to comment Share on other sites More sharing options...

Also do you have lsd or open rear diff? I am not sure. I believe I may have lsd. What would be the difference? What effect would it have on the pathy?

Citron Posted February 12, 2017 Share Posted February 12, 2017 LSD has clutch packs inside. Power can be supplied to both tires, but when you turn, the clutch packs allow slippage so the outer tire can turn faster than the inner. Open means only one tire ever gets power. There should be a orange sticker on the diff that says LSD if it is one. Link to comment Share on other sites More sharing options...

Citron Posted February 12, 2017 Share Posted February 12, 2017 Not to my knowledge. The SE trim package came with LSD and disk brakes so you should be able to get everything you need easily. Link to comment Share on other sites More sharing options...
KovemaN Posted February 16, 2017 Share Posted February 16, 2017 Just make it easy and buy the whole axle, calipers and all. If it's '95 or earlier, everything will bolt right up. Just remember that the automatics had 4.6 gears and the manuals had 4.3. 1 Link to comment Share on other sites More sharing options...

I dont think they would be broken Link to comment Share on other sites More sharing options...
Citron Posted February 16, 2017 Share Posted February 16, 2017 He means the whole axle assembly, including housing. You could replace the seals if they are leaking, or you want to. Link to comment Share on other sites More sharing options...
KovemaN Posted February 16, 2017 Share Posted February 16, 2017 The seals wouldn't need to be touched. You won't even "have to" replace the gear oil, but I would certainly recommend it. Link to comment Share on other sites More sharing options...
SpecialWarr Posted February 17, 2017 Share Posted February 17, 2017 Conversely: we could meet up somewhere around Oklahoma and I'll swap you my rear axle w/discs and LSD for your rear axle w/drums and LSD! Link to comment Share on other sites More sharing options...
adamzan Posted February 17, 2017 Share Posted February 17, 2017 Why the heck would you ever want drums? Link to comment Share on other sites More sharing options...
SpecialWarr Posted February 23, 2017 Share Posted February 23, 2017 Ummm.... I can't think of a good reason other than I've never owned anything with drums before? Link to comment Share on other sites More sharing options...
adamzan Posted February 23, 2017 Share Posted February 23, 2017 Lol. My old pathy had drums. It was okay. The braking difference is marginal, but it is way easier to slap new pads in than playing with springs, shoes and clips at -30C 1 Link to comment Share on other sites More sharing options...
PathyAndTheJets Posted February 24, 2017 Share Posted February 24, 2017 (edited) They stop better than discs before they get hot. More friction surface, and the leading shoe will slip down slightly and push on the trailing shoe and give more braking force. Disc brakes are much easier to work on, especially because you don't have to screw around with getting the drums off. This also neglects performance disc systems like 4 piston brembo stuff.

Citron Posted February 24, 2017 Share Posted February 24, 2017 They only stop better when dry and cool. Drums grab when they get wet, like when wheeling, and heat much faster under load, like coming off of a steep hill. If you have ever driving a four wheel drum vehicle in the rain you would know why disk are superior. Drums on the rear aren't too big of a deal since only 30-40 percent of the stopping force is back there, and every time one grabs it doesn't try to rip the wheel out of your hand.

hawairish Posted February 24, 2017 Share Posted February 24, 2017 Would he need to remove the thrust block in the diff for the swap? Changing the outer grease seal requires completely disassembling the axle shaft assembly...which requires a press, and is a lot of work for a $1 part and likely warrants changing out the bearings while you're in there. Definitely change out the inner oil seal at the end of the tube...noting that I've had to destroy them to remove them. Lastly, there's a large o-ring on the outer lip of the axle tube that should be replaced. Link to comment Share on other sites More sharing options...
PathyAndTheJets Posted February 25, 2017 Share Posted February 25, 2017 I dunno man, I think your drums were out of adjustment, drove a 68 Chevy pickup with 4wheel drums, manual steering and brakes. Didn't pull or anything under heavy braking. Yes It was driven in the rain. But my point was that drums are perfectly fine in the rear, and that they'd probably perform better than the single piston discs on the back of a Pathfinder. That being said, I wouldn't convert to drums. But I'm also not going through the trouble to convert to discs. Not to save me half an hour once in a blue moon if I have to service the rear brakes. 1 Link to comment Share on other sites More sharing options...
Citron Posted February 25, 2017 Share Posted February 25, 2017 It was a friend's truck. Late sixties Chevy, 327 and three on the tree. He was pretty lazy so the brakes could have been out of adjustment, I don't think they had the auto adjusters back then. I agree, not enough of a difference to mess with changing on a rear axle.

SquadCarPathfinder Posted February 22, 2018 Author Share Posted February 22, 2018 Thought this thread was dead but i guess I was wrong . I was thinking about it but I think I'll leave my rear end as it is. And I think I am fine for the time being since my dad and I got brembo rotors for the front along with new pads. Thanks for the responses, I'll probably be posting more of these threads if i think of anything interesting for restomodding our vintage rust buckets .

Steve_RI Posted February 22, 2018 Share Posted February 22, 2018 One advantage with the drums is that the parking brake cables are a hell of lot cheaper and much easier to find versus the disc. Link to comment Share on other sites More sharing options...
adamzan Posted February 22, 2018 Share Posted February 22, 2018 Yeah, and less maintenance on the drums. I seem to replace my pads every other year in the back. And I don't really notice a difference in the performance TBH. Other than the fact that my &^%*ing parking brake doesn't work. 1 Link to comment Share on other sites More sharing options...
OH6PILOT Posted February 27, 2018 Share Posted February 27, 2018 So, I've been watching this post, because I've been wanting to find an LSD with the disc brakes assy for a few years now. Today I finally found what I was looking for!! Everything attached, and not torn up or torn apart!! Best Part...$160 for the whole assembly... Worst part, tearing it off the donor vehicle in the middle of a rainstorm downpour at 45F. Sucked ass. but...worth it. 3 Link to comment Share on other sites More sharing options...
