Title: Does brake caliper size matter for the thickness of the Disk?
Post by: BPLP on March 06, 2018, 09:05:04 am

I'm setting up my breaking system for my racing mower and this is my first ever build so I have no idea what I'm doing. I want to buy a Honda GY6 brake caliper off of eBay and a 8 inch brake disk (8" brake disk - gold) off of BMI carts that has a .16 thickness. My worry is that I'll buy both of these products and have the brake disk be to wide and not fit in the caliper. I have been searching for what the max thickness of brake disk is compatible with that caliper is but I so far haven't found anything. If anyone knows anything about this lil problem of mine, could you please shoot some info my way? Thanks!

(Also I know that these aren't going to last long and I know they are super cheap but I'm not planning of thrashing this thing super hard and I'm a high school student with no money so I can't spend $200 on a break kit.)

I solved my own problem!!! Yes the GY6 2 piston caliper works with up to .16" thickness of brake disk. Perfect for my build!

I used a front four piston caliper off of an Yamaha R1. Works great and they can be had relatively cheap on eBay and was compatible with my 7.25 disk from BMI
