H3 Brake Line Fittings

[MTUH3]

They seem to be some sort of metric size. Any one know what that size is? Oh course Napa and most other auto places only carry standard.

I'll call the dealer in the morning, but I will need to order new flex lines too.

hard lines? I used Napa...Just bought brand new hardlines with the fittings on, Napa had em. For the flexible lines I used crown performance with extended lengths, stainless, DOT approved and available in red

 

[MTUH3]

Yeah, mine only had standard, so I could't get the calipers to connect to the hard lines.

that blows...like you said in the opening post, try the dealer but expected to pay a bit more. If you dont care about time see if they can get some in for you.

I spent all night bending up templates and was ready to go.... GRRRRRRR

So the male ends on the brake lines are metric M10x1. Another Napa store had / ordered the adapters for 3/16th to M10 fitting

Are you changing for added length, or because of corrosion? Some of the H3's have a TSB/recall on the front brake lines for excessive corrosion. Got mine replaced under warranty.

 

[MTUH3]

Mine are getting replaced because I went to a SOA. I may have been able to adapt the old ones, but the nuts stripped off the connectors. I went into the SOA project planning on replacing the lines, so I was not concerned with saving the old ones

I know its a tad late now but, next time...soak em overnight with PB-Blaster & use a flare-nut wrench.

Nothing special about the ends...just go next door to a different auto parts store.

 

[MTUH3]

I did soak em, 6 years of MI weather and living on a dirt rd just killed all the fasteners on the truck. I have to replace all the speed nuts and bolts that hold the rear fenders on too

Off topic to brake lines but on topic to the SOA project and napa.

I don't remember or not if I told up but you need to get the fatter O rings for the rear axle speed sensors. Due to the increased pinion angle the diff fluid will leak out until you put in a fat o ring. Once you do it, it will all make sense! The napa O ring is much thicker then OEM

 

[MTUH3]

Thanks, I have to replace one of the sensors anyway
