Right, media in the blast cabinet doesn't last forever :sunot:

I forgot - I did a complete rear brake job last July. Replaced the calipers, rotors, hoses, and pads. $372. I have edited my original post here to reflect this.

What I didn't include, was that I've already purchased all the parts for a complete front brake job. Found a sale I couldn't pass up. But for now, the fronts have some life left in them.

Did you use the Hayden cooler for the tranny or engine oil?
If it was used for the engine did you run 3/8 line for the cooler, because I was under the impression that the stock lines were 1/2?

I used this Hayden cooler for an engine oil cooler and plumbed it with #6(3/8" equivalent) hose. I would have plumbed it with #4(1/4" equivalent) but the Hayden comes with 3/8" nipples. This vehicle did not come from the factory with an oil cooler. My engine oil bypass filter is the restriction in this circuit, not the size of the hose. Bypass filters do great job of filtering, but the tradeoff is they are restrictive. That is why I went with the small Hayden. The flow rate(gph) thru this circuit(cooler, oil tank, bypass) isn't high, so the small cooler should be adequate. My logic is "a little oil cooling is better than no oil cooling at all".

Our Yukon came from the factory with a trans cooler, rpo code KNP. It's not very big. If I towed, I would put a larger trans cooler on it.

Here's a link(with pics) to the cooler, oil tank, bypass filter install that I recently finished: https://www.tahoeyukonforum.com/threads/mods-because-of-social-distancing.117889/

What time can you be here Saturday? I have the same rig so shouldn’t take but a few hours. @NathanJax can this be a sticky or something?

I can’t believe after 2 years with this truck I missed the relatively easy retrofit for the air filter.
