Front Brake Caliper Replacement - Napa Eclipse NLA? Options?

[Irish Reiver]

I mentioned ealier that made the mistake of swapping old OEM calipers for aftermarket eclipse calipers but i have righted that wrong now and will swap in the replacement calipers when it cools down a little.
Question - i swapped the OEM rotors for Stoptech rotors. Is it worth going back to OEMs or are the Stoptech rotor fine for the remainder of their useful life?

I've just ordered 2 new fronts from partsouq (47750-60060 and 47730 60060)- they were expensive ($465 NZD each) but Toyota here in New Zealand wanted $1000 each and 8 weeks from Japan. Only aftermarket option was Terrain Tamer and they were about $800 NZD new EACH and 2 weeks from Australia. I'll roll the shipping dice for that!

Once I swap in the new ones I'll work out if i can rebuild my originals - I'm not hopeful, they're pretty siezed. One of the Parts shops here can send stuff away for rebuild so might go that route.

I think all this brake overhaul talk here and I may have jinxed myself into doing the rears. Take a look here: Pulling left only on really hard braking - Perhaps someone can give some insight on some additional troubleshooting procedures. Otherwise I am off to Norwalk to baseline the rears...

I don't have any good insight - but this is why i'm replacing my napa rears that i didn't love with new calipers at the same time as the front. Complete OEM baseline for peace of mind. Scary enough driving a truck this heavy that now goes faster than it should with a turbski.

Cruiser Outfitters has 80 series front Calipers in stock....Toyota Reman.

I ordered my rears last Friday from McGeorge but no shipping notification yet.

Well for the sake of my pulling to the left issue and just wanting a nice baseline in the rear, I went ahead and ordered new OEM calipers, rotors, pads and brake lines. Should have everything by Friday.

Where did you order from to get them that quickly?

Local warehouse had everything except one caliper which needed to come from a centralized warehouse, so should have that by Friday. I am able to pickup from Norwalk Toyota when needed.

Just got the shipping confirmation on mine. Should be here Friday.

Received all 4 new OEM a week ago. Thanks to this thread and other’s advice these should be good for another couple decades.

@rolliges I love shiny new OEM parts! I hope to have my rear brake parts by Friday!

Brake line gaskets?

Brake line gaskets?

Yes, copper gasket (crush washer) they don't come with new calipers or in a rebuild kit either one.

Go figure.

Had on hand already along with banjo bolts.

Smart man, be prepared.

I rebuilt (about 7 yrs ago) the old calipers I've just removed recently during my front-end rebuild - I remember I did a lot of work on the pistons to deal with corrosion and was very careful with cleaning and re-assembly. But it was all done outdoors on a bench on a verandah of where I lived at the time so no nice 'workshop' area. What piston options are available? Genuine Toyota's are chrome-plated I believe. Are there any stainless-steel ones around? One thing I do remember is I used a lot of Silvo for polishing the pistons and the piston bores in the caliper halves (again to deal with corrosion).

Pro (!) tip - with the bigger front brakes get rid of shims and use 105 series front pads - DB-1365's. They are a tight fit (you'll need the pistons all the way in) but they give a much bigger contact area. As for the brand of pads to use - that's very subjective. Some will say OEM, some will say Bendix. My current ones are 'RDA Extreme'. They're only half worn so will be going back in with new OEM rotors and calipers.

OEM are pretty good quality. I didn't have any pitting or corrosion on mine but I do keep my brake fluid flushed and clean. Brake fluid is highly hygroscopic (attracts moisture easily) and moisture in the system can cause several problems, not the least of which is corrosion.

I also bead blasted my calipers to make sure I had good clean 'bores' and seal grooves.

You sir do not mess around. I appreciate your attention to detail!
