You'll never find a man to be as loyal to you as this truck.
Good for you,keep it going.....the heck with what those jealous folks are saying...
I had a car that i drove for close to 350k before SELLING it, not scrapping it as they all said is all i could do...
I use to tell folks,that on a really cold morning when i need my woman and my car to turn over,only my car turned over.
OK Brake concern,
Replace both front brake calipers and both front brake hoses to the calipers....the hoses can collapse internally,allowing fluid thru but not back causing the calipers to hang up.
More than likely its just the calipers.
What you can do is crack open a bleeder screw on the seized caliper(s),if it frees up,then the hose is restricted,if it doesnt ,caliper is seized.
Always replace calipers and hoses in pairs...
At this year and mileage i would replace both the calipers and the hoses....make sure you replace the caliper slide pins and lubricate them well with caliper lubricant.
Bleed the system well and all should be good.
Only problem you probably will encounter is the rusted lines coming to the hoses,usually they wil end up needing replacement ,so prepare for that if you do tackle the hoses...and make sure you use new copper washers on the connection where the line bolts to the caliper....2 on each connection
Hope that makes sense
One other thing...you forgot to mention if you love your truck.
OK,gotta ask...whats her name?...i'm sure its a Bessie or a Lulubelle right?
