Brakes better with smaller tire?

Hey Im reconsidering getting 33's (to replace my current 33's) because my brakes are horrible. Will there be any noticeeable difference in braking between 33's 10,50 R15 and 31's 10,50R15? Ultimately I would like to do the vanco brake upgrade but as most of you know money doesnt grow on trees

In all honesty since im busy all the time I dont do much wheeling, and drive about 35 miles each way 4-6 days a week and the 31's are looking pretty attractive. The 33 weights 47 and the 31 weights 44 according to tirerack. Im not even sure its the weight so much as the diameter

Anyhow will my braking performance improve ? Its not good to not be able to stop lol

Breaking will definitely be noticeably better with 31's due to the less rotational mass.

Drive slower maybe? Or anticipate the stop and brake earlier? Braking has only ever been an issue with me when it's an emergency, even then, I've been able to stop in time on most occasions or swerve out of the way.

Do you need to service the brakes? They shouldn't be that bad if you have good pads/shoes/drums/rotors, fresh fluid & a good bleed.

Don't know what type of Jeep you are driving nothing in your profile. So here is what the YJ owners are doing about that. They get a compatible Mastercylinder from the TJ or a Ford E350. Especially when they upgrade the rear toa Ford 8.8 with disc brakes. More volume for more pressure. I haven't upgraded mine with 33s and yes there is a difference but I can still lock the rears no problem. So instead of sacraficing tire size yolu may want to upgrade the Master to see if that helps first.

Upgrade the brakes, don't downgrade the tire! But yes, there is a difference in braking based on the tire size as going from my stock 31s to 33s my brakes now require a little more stopping distance (on a Jeep with less than 1k miles when the tires were swapped).
