I got the P0430 code which is catalyst efficiency (bank 2) and then I decided not to clear it and it went away on its own and hasn't come back in a while now? Any thoughts?

At 160k it's time to do the brake lines. They definitely look like they are getting worn and all I currently have is drop brackets and extensions I believe. I'm reading some bad stuff about the braided stainless lines and I'm wondering what I should go with? I don't mind buying a brake bleeding device such as mightyVAC or something similar since I have the air compressor and I also plan on doing the girls 2004 grand Cherokee WJ. She is due for a bleeding also.

Thanks in advance for the advice.

No input on the catalyst efficiency, just the brake lobes. I bought the braided stainless that is in a thick plastic sleeve, I think they were Rough Country, and they've been great. The straight stainless ones like to catch your hand when you're working on the Jeep. The RC ones were on some insane discount when I bought them so I bought front and rear- total of $34. No elaborate bleeding required, I just filled the reservoir and cracked each line, then standard bleed. They're just as good as when the Jeep was new and on smaller tires. They've got plenty of length for the lift without being cumbersome.

Would they work with my set up. I have the OME HD Springs and nitro charger shocks. Running 305 70r16. Love that price. Doubt I can get it but it should be a few $$ more. Here's kinda the only pic I have on my phone with the brake lines in it.

I know your coils are heavy duty but is that roughly equivalent to 1.5-2"? I don't see why they wouldn't though, the lines pretty well sit out of the way and have plenty of length. You'd be able to ditch the brake line drops as well. I had homemade drops on the rear and they're now in the garbage. I'll grab a couple pictures.

I think it was primarily because of the length needed if I were to disconnect. Otherwise I was trusting an off-road shop back then.

The HD Springs are numbered at 2" but you get more like 2.75" with no heavy front bumper like me.

Yeah, I had that. And it went away. For quite awhile--measure in months or even a year. But eventually did come back. I ignored it for quite a few months, but lights like that do bother me. So, finally swapped out oxygen sensors, no joy. Replaced cat's and problem gone. I was in the vicinity of 200,000 miles, so replacing the cats did make sense. Expensive sense, but good sense.

EHarris

Yea I had a feeling the cats were going to need to be replaced eventually. I'm at 160k. I don't think this is a job I can do on my own along with the state of California has some strict rules on what can be used if not using OEM. Would you mind if I asked how much it ran you? I'm thinking parts and labor somewhere around 12-1400k ?

Mark Doiron

I don't mind if you ask, but I don't have a good answer for several reasons. First, I have an access route to cheaper OEM parts than most folks. Second, I put it off until the cats were being pulled for another reason--To replace the clutch throwout bearing--so labor was a sunk cost (it's possible to replace the TOB without pulling the cats--but the one time I did it myself with some friend's help it was a pain so we ended up pulling it to get it out of the way). Third, the fellow who does my heavy-lift mechanical work is a friend and charges me a lot less than a dealer would charge you.

Sounds like a good excuse to do a BBK upgrade if you haven't already. The Mopar BBK comes with replacement brake hoses.

Keep us posted what you find out on the cats. I now have 165K miles on my 2009...been dreading the thought of replacement exhaust parts especially the cats.

Rednroll ive been using the Bosch quiet cast and they have a 3 year any excuse warranty along with the autozone ceramic pads lifetime warranty. I do rotors and pads every summer for free except after year 3. Then I have to shell out for new rotors again. I like fresh brakes before long summer trips. The lifetime pads I started at 50k and have at least got 7 sets free so far.

I'd rather spend the money on other upgrades if possible but I've heard great things about the big brake kits. Maybe if I had to do the master cylinder at this time too but it all still looks pretty good.

Anyone get a mightyVAC? I have an 80 gal air compressor and would love a way to bleed them with something like that but I hear good and bad things especially if you don't have a way to activate the ABS. My girl has the 04 WJ so it would get double use.
