Speedymaru Posted November 14, 2019 Report Share Posted November 14, 2019 I’m attempting to get my 620s brakes working, and I’m having some issues with the front disc brakes. I removed the caliper, and I cannot find a replacement. Autozone said they no longer carry them. I already ordered new rotors. I’m thinking of doing the d21 swap, and I’m mainly just curious about how much the d21 parts should cost, and if there’s a way to locate stock calipers. I’d prefer to stick to the stock system if possible, because I’m assuming it would be cheaper and simpler. This truck is not a daily driver, so I’m thinking the stock brakes should cut it. Any help is appreciated Quote Link to comment
datzenmike Posted November 14, 2019 Report Share Posted November 14, 2019 I think the D21 would have roughly the same amount of parts so equally simple. The D21 is likely easier to find parts for because newer. One hell of a brake upgrade. Quote Link to comment
Speedymaru Posted November 14, 2019 Author Report Share Posted November 14, 2019 Okay. Is there any way to locate stock calipers? I may be overthinking the d21 upgrade, but it sounds like it would end up taking a lot longer and cost a lot more Quote Link to comment
datzenmike Posted November 14, 2019 Report Share Posted November 14, 2019 Auto supply like NAPA, Rock Auto?? They may have them on an exchange basis. If they are not seized or leaking they're fine with new pads and rotor. I've rebuilt 4 piston Toyota truck calipers... it was easy and I was extremely happy with the outcome. The rebuild kits are ridiculously cheap compared to re-manufactured ones that are questionable. I don't know if they are available for the 620 from Nissan still or not, maybe MAPA, RockAuto? Maybe you don't care to do this sort of thing. Try a want ad here... https://ratsun.net/classifieds/category/9-datsun-parts/ ...someone may have a set laying around from a D21 swap. lol.

Speedymaru Posted November 15, 2019 Author Report Share Posted November 15, 2019 Thanks, I’ll definitely look into rebuilding them. I really appreciate the help! Quote Link to comment
mklotz70 Posted November 15, 2019 Report Share Posted November 15, 2019 Since your 620 has ball joints, the easiest way to upgrade is to simply swap the entire spindle assembly from an HB into you truck. Disconnect the brake line at the frame, the tie rod end, the two ball joints and swap the entire unit. If you want, you can do this with dropped spindles. If you find donor setups with good rotors and calipers, but swap everything out, bleed the brakes and you should get an alignment, but it may not be necessary. You'll get vented rotors and parts that are readily available when they need to be replaced down the road. 1 Quote Link to comment
