I have started putting together a page for AndyZ28's 1LE upgrade. It is far from complete.

Cool!

 

Looks good so far. This is going to be a great resourse. Thanks.

See the other massive post for major problem that I have suddenly encountered with my 1LE front brake upgrade. It really sucks,and I don't know what to do.

 

Andy, you addressed the bearings a little earlier, but did you have to use different bearings for the new rotors? Jayg did not list them on the "parts list" on the upgrade page, http://www.geocities.com/rgades/1LE.html?985331453350

Thanks...

 

Dammit...I can't read today. Thanks anyway..

 

The bearings are different(larger). As soon as I get the #'s I'll post them. I think we have a Timken part #, I'll check. JAy

 

How much did this cost will the 1le brakes fit under the 4th gen 16*8 rims?

 

92formula, check out this thread in this section: https://www.thirdgen.org/messgboard/...ML/001248.html
This should help, although the prices may not be spot on.
And yes, it will fit 16x8 rims..

 

AndyZ28/Jayg, I have Q for you. What type of rear brakes are on the car that you've been working on? If they're discs, have you upgraded them also or do you plan on it? Also, how were the 1LE rear discs different from standard rear discs? I have to rebuild both my front and rear discs so I might as well upgrade both sets. Any suggestions? Thanks again...

 

Yes my car has 1LE rear brakes also. It somehow had a 9bolt rear with these brakes already on it. I will take some pictures of them later,and post them.

 

As for the bearings. The Timkin part# is M12649. If you will look at the "bearings" on the website.You will see the part # on the box.

 

For those of you that have been following my 1LE front brake upgrade,along with "jayg". I will soon be posting some little known 1LE info. That will be something of a bomb shell.
No kidding. But I will have to wait till I can set it it up with jay. When I found out. I was stunned.

 

So Where's the bombshell?????

Hunter,You already know it! Here goes.If you are planning to do a GM part 1LE front brake upgrade. You'd better hurry. I am told that the GM 1LE parts are running very low. The spindle bracket (GM calls it a plate) part#18016034 is down to less than 250 in all of North America. With 2 required per car. That means their are only enough to do 125 cars. Also GM part#10132829 the caliper carrier RIGHT side.Less than 50 inall of North America. With 1ea required. That means only 50 cars can be done. GM# 10132930 Left caliper carrier only 84 remain. Better hurry!

Good thing I just ordered a set then.

 

And they are no longer in production!

 

Yeah, I was'nt sure what you were refering to, Sorry Andy.

Anyway, Andy is correct about the caliper brackets/plates. No longer in production - limited supplies available.
However, there must be another source somewhere, I just haven't found it yet, because Bear still uses this caliper in many of their kits, ant they use the same bracket, or one that is virtually identical. The Corvettes also use the same bracket, so somehow there must still be a source out there. Gotta find it!

You just lit a fire, Andy. I'll be at the dealer tomorrow. Thanks for the info. My credit card will be cussing you though.

 

I got my brackets last night from gmpartsdirect.com. Their prices were very good compared to the dealers. For example, P/N 18016034 was $85.11 at the dealer and $57 at gmpartsdirect.com. , P/N 10132829 & 10132830 were $95 (dealer) compared to $57 (online), then add $9-16 bucks for shipping PER PIECE. The shipping, in my opinion, was a little high for all the stuff, but I still came out ahead in overall price. No dealer had any of the brackets or plates in stock, and all were the same in price. I also ordered the bolts and washers and still came out ahead. FYI...

 

ebmiller, I'll bet you're not the only one hot footing it to get the GM stuff. By the way. When you get a little closer to the upgrade,I have the torqe specs for the bolts.

 

I just ordered the two plates also, but from Dal. It comes to about the same price as gmpartsdirect.com, since their shipping is unbelievably high. Dal has pretty good prices and charges normal shipping amounts.
I would like to thank Andyz28 and Jayg for putting this together. Mike

 

Now, has any body been able to get stainless braided lines for these brakes lately?

I'm trying to get the Earl's kit PN 28A190. Summit lists these as out of stock and can't be ordered. Jeg's didn't have any such warning so I ordered them from there. I'm beginning to think that might have been a mistake. They haven't charged my credit card yet either.

'99 Navy Blue Metallic Firehawk #120 M6 (99.44% stock) -- daily driver

 

Another question, does everything fit inside a 15" rim or does it have to be 16"?

 

Yes, The entire package fits rather nicely inside the 15" wheels that I got from an '89 RS. I like the look of the stock '82 Z28 wheels. But I wanted 15". So I found a complete set, As soon as I get together with jayg. We'll have some wheel pictures also.

 

Andy, I think I might have asked you already, but what did you use to modify your spindles? I noticed that Jayg had "more to come" about this on the 1LE page, but I'm curious. Yours turned out real nice in the photos. Also, any reason you didn't opt for the above mentioned braided stainless lines? I probably will when I get around to doing my upgrade.

 

I used a band saw.As I did not want to use any type of torch,or heat at all. I did not use the stainless steel brake lines because they are just too expensive for me. Besides if the stock 1LE brake lines were good enough for GM. Then they are good enough for me.

 

Interesting note... the parts department at my local dealer says it seems the same outer wheel bearing is used in all 89 Camaros with heavy duty suspension (IROC, Z28), whether they have the 1LE package or not. GM's P/N is 457049, AC Delco's is S-7, and inside the box is a Timken M12649 inside an M12610 outer race. Make sense to anyone?

 

That's news (good news) to me!! Also some more cool info for youze guyz. I was looking in this months issue of Chevy High(who can afford it)Performance magazine. And low and behold Scroggins-Dickey Chevrolet has an ad for a "1LE upgrade kit" $849.00 (or something like that) it includes. Get this; two rotors,and a set of brake pads. Yes that's a period. I dunno about youze guyze. But I did the entire upgrade for less than that. WHAT ARE THAY THINKING??

 

How many wheel bearings would be needed?

 

One for each side of the car.

 

Another question
I was looking in the parts book and I saw a pin #10140666. Do I need these? Thanks

 

That's the caliper guide pin, you'll only need them if your calipers or pads don't come with them. I don't remember if it's 1 a side or 2 a side you'll need.

 

The car requires 1 per side. They often come with the new brake pads. Mine came with the calipers.
The book shows these pins being installed from "inboard to outboard" . But I was unable to do that, because the brake fitting,and bolt were in the way. I had to install mine from "outboard to inboard". Did anyone else have this problem??

 

Mine too.

 

FYI, guys, I received the stainless steel hoses from Jeg's last night. All five.

 

For those that have completed this, how long does it take (Total consecutive hours)?

Also, how did you determine the correct position and angle to cut the spinde ears? I will have to have this done since I don't have a band saw.

Thanks,
Matt

 

Matt,Jay and I will probably be upgrading the web page again this weekend. We have some better pictures of the modified spindles. I am going to add some graphics to the pictures. That will make it much easier. You do not actuallt need a band saw. The band saw just makes the task easier. The forged portion (the part that needs to be cut) of the spindles is actually rather soft. So you can cut it with a good (Starret) hack saw blade. It has been done that way before. Hope that helps you out.

 

Matt_91RSTPI
You don't need a band saw. I used my 4 1/2" grinder with a cut of wheel. Worked great Plus you can use it to grind off more if need.

 

Their is also a good photo on our web page that shows important areas of required clearance. This will help a lot when cutting the spindles. Use '89-'92 spindles.if possible.

 

Andy, what's the advantage of using 89-92 spindles? I can probably score a set cheap and modify them before I do the swap to save a little install time. FYI, I'm still waiting on my brackets from gm parts direct that shipped last week and I'm getting anxious!!!!!

 

Hawk, what did Jegs charge you for the hoses and what was the p/n? Thanks....Ed

 

The'89-'92 spindles have more materiel at the locations where the drilled and tapped holes are to attach the plates.
I don't blame you for being nervous about the GM 1LE parts. They may already be out of some parts.

 

It turned out that they didn't have my address correct on the box so they returned the parts to the dealer. I got them yesterday and I'm going after spindles today. Andy, you mentioned sending the torque specs to me, but are they any different than what would be in the tech manual? Just curious. Thanks.

The P/N was Earl's kit 28A190. I believe it was ~$93 with shipping.
