Can you please clarify that . . . ?!
Rusted out brake lines . . . ?!
Warped brake rotors . . . ?
Bad brake master cylinder . . . ?
Worn out brake pads and rotors . . . ?
The car is cheap enough . . .
If the car is in good shape besides the brakes . . . assuming it’s only going to cost a few hundred to fix . . . it might be a wise choice
but you know your brother, and we don’t
Does he maintain his cars well . . . ?
Or is his idea of maintenance treating it to a car wash and premium gasoline once in a blue moon . . . ?!
We also don’t know where you live . . . depending on where that is, a 19yr old car could be a rust bucket which will never pass safety inspection
