Dump the car. The brakes will be only the beginning of your troubles. Is it a 4x4?
Yup.
And the 3wd works excellent.
Two years ago I put new carpet in it, new headliner, and did mass electrical stuff... then, all of last year, I put less than 200 miles on it, I have it more only so when I need it I got it to haul something or if the weather is crap...
Cost me 50 bucks a year to keep it registered and it’s old enough it doesn’t require a smog test, so what the hey...
and I have broad form insurance so it doesn’t cost me anything additional insurance-wise.
Never, ever, dump a second generation Blazer. They’re just too awesome.
