xofit Posted August 6 Report Share Posted August 6 Hey all, I've had bigger tires on my '78 620 for a while now and the front disc brakes do fine now but I was trying to look into if there are any good disc brake upgrades for the 620. Possibly something that I don't have to swap knuckles for, I've got a hard body and they look similar but i doubt it would be a slap and ship job if you know what I mean. Just need more stopping power at the moment cause the solid disc single pot calipers don't even have enough umphh to lock the tires any more. Appreciate it! Quote Link to comment
iceman510 Posted August 6 Report Share Posted August 6 I don't have all the particulars in my head, but search on here for some threads. You are lucky you have a disc truck already. I believe Hardbody (D21) spindles do fit and give you the option of those brakes. I am not sure what hubs/rotors etc. you use in combination. 1 Quote Link to comment
mklotz70 Posted August 9 Report Share Posted August 9 You might try ceramic pads if they're available....they'll stop like organic, wear like semi-metallic and the dust created has a different static charge so it doesn't build up on the rims as bad. Otherwise, sorry, but there's nothing for those knuckles. You can easily swap to HB(post '85) spindles. Disconnect the ball joints, tie rod and hose and swap them over. You can swap the entire assembly or just pieces if you do just the spindles. You can use dropped spindles if you want to be a bit lower. For what you want, you'd probably be better getting just the spindles, then get v6/4wd rotors and 2 piston calipers....you can use your 620 hubs. I know the HB setup will fit stock steel rims, but I'm not 100% if the v6 setup will. More hub info.... http://www.bluehandsvideo.com/hub-info.html You could also convert to 5 lug with the HB spindles....if you really wanted to...http://www.bluehandsvideo.com/5-lug-swap-nissan-d21-hardbody.html I know ceramic pads are available for the HB setup. Considering how many guys are drifting HB's these days, you can probably get even more aggressive pads if you look around for them. You can also get drilled and/or slotted rotors for the HB setup....probably for the v6 version, too.....http://www.bluehandsvideo.com/rotors.html Quote Link to comment
