1999 Cadillac Escalade jumps a little bit

Cadillac Escalade

I just bought this car and before I had it looked at by a mechanic because when u stop or accelerate it jumps a little bit. He said it was to do with a leak on the breaking system and some breakers, and it will cost $300.00 or so. I’m scared to have that fixed if its not the problem. I don’t want to spend 300 for a transmission problem. Oh, and the people I bought it from didn’t drive it for a few months and then this happened, it did have a leak of brake fluid though by the tire.

First off the brake fluid leak should be fixed as it is a safety issue. Second the brake fluid leak has nothing to do with a transmission. More than likely the leak would cause some drivability issues and once repaired, it work as it should.
