Silly brake question

[4DoorBlackTop]

I am bleeding the brakes for a friend. Do I need to be concerned about the rear drums?

I bled the brakes on my K5 Blazer years ago, but didn't mess with the rear drums, I was fine. That's why I am asking..

Thanks!

P.S. yes it's a serious question. Sorry I don't know anything about cars.

They're probably weren't doing much on your K5. But yes, you should be bleeding the drums too. The biggest problem with brake issues where drum brakes are present is usually people not adjusting the drum brakes properly.

after a repair or just a flush/quick purge to get rid of old fluid?

you should but ive replaced masters plenty of times and just bled em at the master fittings without any issues

Be careful of the bleeder screw on the wheel cylinder. That's the thing that push outwards against the brake shoes. I snapped them off once on my old truck and ended up having to replacement. Not a big deal, but it was a cost and time I hadn't allotted for.

I personally would bleed the rears, just to make sure you don't have any air in there. Start with the one furthest from the master cylinder.

headsup folks put a dolop of grease over your filter linenuts and bleeder screws
hell coat all your lines in grease
i know of a 210k 96 bonnie that still mint underneath cause since 98 its had 18lbs of grease protecting it

take a drift punch or heavy screwdriver against the sides of the bleeder boss and give it a few raps with an oil or penetrating lube on it

you can do this easier with a caliper bleeder

the worse it looks spend longer raping on it before you try and back it out

the master tends to be the high point so just keep your service point / open in the hydraulics near the top and you can backbleed

My friends Kia Sportage has air in the lines. I was hoping I didn't have to mess with the rear drums. It looks like when the screw comes out it will break.

Always, ALWAYS, do a good bleeding on all four corners whenever the system is opened
