Seized front brakes - 1981 GMC Sierra Grande 2500 Camper Special

[SFP]

So....

Front brakes on Fozzie (GMC) seized today while I was picking up a new BBQ.

I called the shop to ask about getting new pads and they say callipers as well.

Then they ask... 11" or 13"  Any idea how I identify that without taking the wheel off and measuring?


Recommendations for new pads and callipers? Anyone have any feedback?

Thanks again folks.

by using the second one you can kind of guess by looking at your master cylinder if you have the jb7, jd7 or jb8 then you would have the 13"

if your gvwr is 8400 or above then it would be the 13"
if you have the 14 bolt rear axle sf then its the smaller brakes

when you say "seized" do you mean the grabbed and wont let go or after a few seconds then will finally let go?

Locked up calipers are common
It's usually the old rubber brake lines that go to the calipers
They swell up and get clogged inside
