Blew a Brake Line, In process of replacement... BUT ?

gmtech4 · August 26, 2014

a couple of days lmao !!!

Only issue is a possible frozen bleeder screw. That happened to me all the way around with my 04 and so I just bought new calipers (from auto zone about 70 bucks each)

Pete, ya remember the conversation about being Optimistic ? Well we can throw that right out the window !

After reading the above quote from you I ran out and soked the bleeder screws with penetrating oil last night. This morning I attempted to break them loose and BREAK them I did ...LOL Got luck the right side....

NOT SO LUCKY ON THE THE LEFT SIDE !

Picked up the rebuilt caliper and a pair of bleeder screws at AutoZone for $65.00 and installed them.

Also managed to free up all of the lines from those plastic brackets along the frame rails. I'm ready to replace the lines once they show up !

I'm not surprised! Glad it's going smoothly overall though. Just a thought for you.. if you want to spend the time and money, you could put on some braided stainless flexible sections at each wheel. It will give you a much firmer pedal feel!

I hear ya....been thinking the same thing ! Might as well considering I have gone THIS FAR !

Got another question....I got told this just a few moments ago..."Replace BOTH CALIPERS at the same time or you'll end up with a bad BRAKE PULL....." I never heard of that and I have replaced only one caliper a few times on my other rides and never had a problem !

I've heard that as well and also have only replaced the defective calipers with zero problems. Personally unless your putting a different type of caliper on compared to the other, you will be fine.

I figured as much...Thanks for confirming this Mark !

Yeah I agree. It shouldn't be an issue because it's all oem spec parts.

Just came from my Chevy dealer and had checked the price for a pre-bent brakeline kit for my Silverado.

This kit is a 7 piece, stainless steel, nylon coated kit. Part # 1-22932587 which is for (among others) a 2004 Silverado Z71, Extended cab, 4WD, 5.3L engine (the one in my pic at left). They checked the application using my VIN number.

Total cost for the kit is $124 plus change.

Not a stock item due to the number of different kits available but overnight delivery usually. I ordered it!

UPDATE:

I just happened to check Amazon.com and found the same kit listed (use part # 22932587, omitting the "1-")

for a grand total of

$62.23 with FREE shipping.

Well it's done...The kit I purchased went in fairly well. Had a couple of minor issuses with the bends, mainly at the ABS Unit and the Distribution block under the Master Cylinder, but for the most part it was a success. Took me about 6 hrs total for the install, lying on my back . A second set of hands would have been helpful but i managed.

Using a hand operated vaccum pump I was able to bleed 90% of the air out of the system. Again a helper would have been nice so I could of bleed it the old fashion way. So I got enough brakes to get me to work and over the weekend when no ones around I'll grab one of the guys, put the truck on the lift and bleed then again.

Thanks so much for all of your help...Greatly Appreciated !

I just ordered the kit from GM for my parents 2004 Silverado ext. cab. It was mine and I sold it to them a year ago. The thought of them driving it and having the brakes go out was too much for me. Especially since I had prior knowledge of a problem. I really wish GM would just do right by these brake line rust issues and fix them for us. My GMT-900 has all nylon coated lines from the factory. Looks like they finally figured that out.

Question-

Did you have to remove the body from the frame to get this done? The instructions call for that, but it seems like it would be doable without doing that.

it IS common to replace both sides in steering and brake components for safety sake ,,,,,,thats why owners shouldnt be repairing their own brake and steering parts

Sorry running it dry does NOT require a bench bleed

Yes running the mc does require bench bleed in order to get all air out of system, assurance is key when safety is on the line. GM ASE certified technician here. Here is why. Theoretically you wouldn’t have to because no air is introduced until you go to bleed the system hence taking off of the cap off of the mc. I know this because I have seen coworkers who have run into this problem...... bad day for them... but I guess if that’s okay to run the risk with you go for it.
