What to do with these tii calipers?

[mvliotta]

Hi everyone,

 

Want to address brakes over the winter as I have a steering wheel shake on downhill braking and a slight pull to the right. Seems like a warped rotor from what I have been reading. 

 

Pretty sure I have a stock tii brake set up. 

 

Picked up a pair of used tii calipers in case they would come in handy. They were sitting around for a while.  This is what one looks like.

 

What should I do with them?

(BTW, my neighbor does NOT have a pool!)

Rebuild them and here’s how

Clean them up, reseal them and run them.  Takes compressed air, maybe an easy afternoon, and not

much for a couple of seal kits.

 

If you want them to look really good for 5 minutes, you can electrolyze them.

 

no, not like your unibrow...

 

heh

Thanks for the quick replies, gents!

 

The article Buckeye attached has the pictures I was looking for as they are missing in the tech articles section.

A safer but more messy solution is to use a grease gun to pump the Pistons out, advantage is that as soon as they pop there's no residual pressure to project the Pistons across the workshop. Make sure all Pistons move before the first one ejects, otherwise you can't apply pressure to the stubborn one..

Chunks of wood the right size help to keep free pistons in the caliper while the compressed substance 

works on the stuck one(s).  

 

I too was a bit scared of the first few I used compressed air on, but a heavy towel

wrapped around the whole caliper, then securely fastening the caliper into

a vice makes it pretty dent- free.  Plus, the design of the caliper is such that, with abovementioned

wood in place, the pistons don't go too far.  Just don't put your hand in there!
