GMC Bad Brake hoses

James —9

Coming in to the shop before the sun this morning, you can see the American Dream driven by Mac the Fire Guy, he’s here going over the plans for the upcoming GMCMI convention in Dothan.  He’s coming to show you guys a real fire safety show…. if you’ve ever seen his talk brother, you just should not miss it.Mac-at-shopSpeaking about the Dothan rally, I’ll also be there as well talking a little about how to design your new interior also a talk about Manny’s new 1 ton front suspension and the new turbo diesel.

Hey, got get another cup of coffee and maybe that show, I’m breaking bread this morning with Mac…. be right back…

Oops, long breakfast, sorry…. The day is on but I’ll pust throughout the day.

Here is the tool you need to use to remove the rezar panel screws.  Gotta break it loose with superior torque….

Bill-breakdown-3.  Take a look at your rear brake hoses, if the shoulder where the attaching bolt goes through the fitting is rounded like this one… brother THAT is an original 40 year old brake brake hose man….. DON”T DO THAT  original-brake-hose  Hey and look at the bulge at the end of each hose, that’s rust under the loose rubber sleeve .  These are our Teflon lined, brainded stainless steel brake hoses.  SS-brake-hose-1  The rear hoses are $60.37 for each side.  Bolts into the same placeOld-and-new-hoses  Brake fluid attacks nitrile rubber, brake rubber parts should not be over 7 years old.   Again, here’s what you look for …. a rounded shoulder on the rear center manifold on the rear brake hoses   Bad-rear-hose-4   A dead giveaway is this silver tag if it’s still there…. it will have the production date on it if you can read it  Bad-rear-hose-1  And of course the swollen end fitting is the rust under the sleeve  Bad-rear-hose-2  All of this stuff is an indication you need to do something and if the front brake hoses are ribbed Old-front-brake-hose  those are original too!  Brother those are Bad Juju as well.  Sorry but you just cannot rely that your brakes will work with these 40 year old parts.  “Out of sight, out of mind” I get but with brakes…. naaaaaa!

BTW, while we’re talking about brake parts that go away with age, here is your original brake combination…. meter, proportion or whatever you wanna call it valve with one our never brass valvescombo-valve-3  This original steel valve rusts on the inside from the water attracting brake fluid.  Whenever you do a complete brake job or even doing maintenance you may want to go ahead, brake those 5 lines going to it loose and replacing it.  A direct bolt in combo-valve-4  This part is $89 new and made of brass so there will be no future rust goin on.  By this time seriously, you really should give this part a gold watch and replace it with new….  combo-valve-5  So get out there and get those brakes reliable remember…. it’s awesome if it runs, but it’s gotta also stop!

OK, the day is on and I’m on it.  Thanks for dropping by and thanks for your support……

      Guys, I’d love too. I have a “101” talk on about anything you can ask… I mean after 22 years of this I can at least tell you what NOT to do! Maybe this year I can do that. I’ll be at the Dothan, ask me more then.
