how hard is it to change the brake hose on a 1980 gmc truck?

Answer 1

provided you have a flare nut wrench so that you don't round over the fittings, its not difficult at all. If its a brake hose you're either at one of the wheels or going over the rear axle. If you're changing one for one of the wheels it helps to leave the hose clipped into the bracket while you break the connection using 5/8" (?) wrench to hold the hose and the flare wrench (3/8"?) on the fitting side. NOTE: I don't remember when GM went Metric on there trucks; you may have metric fittings instead of standard on the brake lines. I think the metric lines are 12 mm flares but I'm not certain.

Once you have the connection loose you can then remove the banjo end from the caliper or wheel cylinder. then use the disconnected hose to unscrew the fitting from the line on the other end. Then replace the hose

for the line over the rear axle you'll have flare nut fittings at both ends.

you shouldn't lose too much brake fluid during the change but bleed the brakes non-the-less after you replace the hose.

hope that answers your question
