upgrade brakes w/ lift?

[08medic4x4]

has anyone had issues w/ braking after putting on their lift? I'm going w/ cornfed 3/2 and wonder if it's needed or not.

I think problem would be caused by larger tires and wheels not necessarily the lift.

I think problem would be caused by larger tires and wheels not necessarily the lift.

I agree. The braking issues can be attributed to a combination of two factors, each concurrent with the above statement.

1) Larger diameter tire means the vehicle is actually moving faster, thus the rotors have less rotation for a given speed, which means less surface area contact with the pads, which means less braking ability.

2) The larger tires and wheels are heavier, and have greater built up momentum, and require more stopping power.

Add the extra weight added with gear, camping supplies, etc. and you end up wanting 231mm brakes.

A spacer lift won't affect your brakes, bigger tires will.

I have been running a Cornfed 3"/2" lift with larger tires now for a couple years. I originally had 285/70/17's and am now running 275/65/18's (with 18" rims obviously). I have not noticed a difference in brake wear but my stopping distance has gotten worse because of the increased weight of rolling mass at all 4 corners. A lot of members have been upgrading to ceramic brake pads and stainless brake lines to accomodate.
