On till you get it straightened out do one of 2 things. Park it or put the correct size tires on it. And if it's not right with the correct size tires. Park it. It's a danger to all on or near the road including yourself.

Its been fine , its not the tires etc , it just happened and i haven't driven it since they problem started , just tried to fix it

How much of a lift did u put on it

Look heres the easyest thing to do go get a brake booster for a 2500 that's what I had to do when I lifted my 81 Scottsdale
