I think my brake line is clogged... here is why...
I noticed that my brakes felt extremely weak a while ago (only after driving someone elses truck).
I tested them out on some gravel.
Speed up and slam on them to see if they lock.
Fronts lock (reluctantly--with a lot of force)
Rears don't lock up.
The rears do put some pressure on the wheels when off the ground.
So I take it to an expert
Well it turns out my calipers are seized and it is a $1000 job.
Because the first one said the wrong thing...
I let the second one replace my pads and asked him to flush the system (which I think he did not do).
So I get the truck back and it still brakes like CRAP (but about 10% better than before).
Still rears wont lock and the truck really doens't stop.
So I thought...
Maybe the first guy was right...
Maybe the rear calipers are partially siezed
Next I find some remanufactured calipers for $54 each (with pads).
I put them on the rear. bled them. and ... SAME THING.
They kinda stop...
I think there is rubber or dirt or something clogging the rear.
You know that little rubber washer that used to be on the master cylinder cap?
Not there... deteriorated. Maybe a piece of that is lodged in the brake line, bathing in brake fluid?
How would I go about fixing this?
Can I drain the entire system and blow compressed air throught the lines?
What should I do?
