I rebuilt my calipers today.  Replaced the pistons, seals, and the transfer seal.
Went from this:

I took a bunch of pictures.  It was easy, but I had the use of a media blaster to clean all the rust and crap off, and a special jig to hold the calipers in a vice, and a special tool to seat the seals.

Still have to put them back on the car and see how they work.  My old pistons were pretty poor -lots of pitting.  The old seal were shot - didn't leak, but they were old and wasted.  I am hoping that my left front wheel will no longer lock up before the right front.

New wheels and tires are on the way and I have to install my new rev limiter...almost ready for autocross to start.

Dude!   :023: :023:

Great job!!  ...  I'm impressed.

Don't be impressed....it's not real gold  :icon_razz:

Just a rattle can of engine enamel I bought at NAPA.  I do hope they work better.  On the driver side one of the old pistons really didn't move much - figured that out when I changed brake pads and couldn't push the piston in.

Good job TJ, they have to work better than mine.

I have 4 wheel drums or aka "push and pray brakes".

Here's a picture of one of the calipers all cleaned up and put back together - before I pimped my ride and painted it gold.

I am going to run in G Prepared this year - if my tire choice works out anyway.

Weren't you in HS last year? What are you doing to the car that puts you all the way into the prepared class?

going from this to this:

Changed some other things as well, but tires are the driver since there are no R compound 10" tires.  Yokohoma A032R are available in the right size, but technically not DOT approved in that size.

UPS man brought me new tires today....it was a good smell to open the boxes.

can I send you mine?  I could use that work .... I was thinking of just buying new calibers

Who's mounting the tires?  Or more importantly, did you have any trouble finding someone to mount them?  I bought a 10" wheel and tire to use as a spare (the one I have is 12, but the MiniLite clones are 10) and found a warning to only hand mount the tire to the wheel because of the high possibility of damage?!?!  I've never had to dismount a tire (touch wood) on OC.... and I haven't found anyone to replace Mike....

BJ,

New pistons and seals cost me around $120...that's way cheaper than new calipers, especially the 7.5" ones.

If you want to send yours up here and buy the parts I can rebuild them.

I haven't got the tires mounted yet.  My current tires I had mounted at the Kramer tires down the road.  I am putting the slicks on my 10x6 revolution wheels and getting a new set of 10x5 minators for normal use.

TJ - Call Chuck at Firestone over by Chesapeake Square Mall about mounting your tires (unless you know somebody). I don't have the number handy. He's a racer and knows his stuff about mounting race tires. Tell him I sent you and he'll help you out.

He'll cuss me later about sending 10" tires his way but I'll tell him it's practice for when I need them. Just kiding, he's good people.

Thanks Roy, that's close to my house.  I'll go there and see Chuck.

Nice work restoring those calipers. If you had left them unpainted,I'm sure they would quickly have a layer of rust just from air miosture alone? Does painting them cause heat retention? or is it not that important.

I kinda like the clean look and thought clear coating them would retain a "Like New" look longer.

Nice photos too, is that Photobucket?

Not sure about the heat retention.  I used high temp engine enamel to paint them.  I too liked the cleaned up bare metal look, I just wanted to paint them to keep them from getting all rusty again.

Yep, photobucket.

Those calipers look wicked nice!  Your car is lookin real good all around, and that new rubber ought to work nicely on the Revos, You'll have to take me for a spin in that monster once the new shoes are on!

Roy, 

Chuck is good people!  I owe you one.

Here's the new tires mounted....

Assuming I can get all this rubber inside my fenders, I'll have a little more rubber for auto-x ing!

Shawn,

My new wheels are a little like Sparks'..they are 10x5 Minator's...I put my old A008's on them...they are an inch skinnier than my revo's---not sure how they will look with my fender flares yet.  The slicks will be just for auto-x.

Those look nice!  Might have a bit of a rubbing issue.  What is the offset on the Minators?  I like the machined lip on them as well.

Shawn

I'm glad he fixed you up, I knew he would.

I gave him a heads up that you'd be coming a week or so ago.
And I was right, he called me yesterday, cussing the whole time.
