Overall Assessment

Customers find the product, a brake kit, to be of high quality with precision cuts and professional anodization. It's appreciated for its adaptability to different older truck models, including a 1939 Chevy, with some modifications required due to vague instructions. The product also stands out for its affordability in comparison to complete conversion kits, and its easy and quick installation. However, customers suggest it could be improved by including an option for 5 on 5 rotors and better instructions. They widely express willingness to repurchase, complimenting the fit and caliber.

will work on '39 chevy truck... with modification

installed it on my 1939 chevy truck... but you will need to make/fab a inner bearing spacer for the bearing adaptor thats included in the kit, because of the smaller 39 inner spindle journal. as far as proper instructions.. there are none!!! horribly vauge about what all the spacers actually go. also it seems the top caliber bushing has to be removed and discarded for the caliper mounting pin/bolt head to fit in the spacers place. again... horrible instructions!!!!

good but

they are easy to put on the truck, but they need to have the 5 on 5 rotors option. just in case some one put a rear-end that has 5 on 5 on the axle.

Would be nice to have an adaptor for Astro Van rotors and calipers (5on5, 6on5 rotors) Then can use Astro/Safari Van rims.

Do you have a YouTube video for the conversion? There are several areas of the PDF instructions that are confusing... A DIY video would really help.

Disc Brake kit rotors Hello! Will this kit bolt directly to my ORIGINAL 49' Chevy 1/2 Ton Pickup spindles? Can I use the ORIGINAL steering arms? And will the rotors and calipers from your 48' Ford brake kit work with this kit? Thanks guys!

Are the bearings & seals included in this kit? It says in the PDF you replace the bearing race with the included A13 race, but I don't see the bearings in the picture. Thanks
