Can't figure it out...

On the front calipers, there were little hairpins that held the guide pins captive.

I can't see at all how the guide pins are held in place on the rear calipers, and need to get them out quick. Don't see any hairpins or retainers or anything.

Anyone help an old guy with bad eyes? :)

Thanks guys!
 
Page 9-14 in the Chiltons I have tells me they're not kept with any hairpins, and rather they are to be driven out. Must be a tapered pin I guess?

Don't want to break anything on a Saturday morning...
 
Yes they are pressed in. Very easy to get out with a hammer and punch. If they come out and are a little rusty. Take them to a wire wheel and lube the Ron Jeremy out of them.

They have annular springs that snap into the back of the caliper.
Tap out, tap in (with a suitable drift).
 
I use a small punch and hammer to drive them out from the outside of the caliper on each side. Be careful not to lose the spring against the pads. Then when installing them I use a long brass punch so I can hit the end of the punch with a hammer to drive them in. Because the spring is in the way of a direct shot. Or you can press them back in with a large angled slip joint pliers.

Exactly what I ended up doing to get 'em back in, long brass drift through the coils.

Thanks for the replys, guys. Was in a rush to knock the rears out this morning as we had our installation of officers at the lodge this afternoon.
 
Use a pretty small drift, and tap them out from the backside. Also make sure to fully seat them with a drift & a tap from the hammer from the "outside"upon reinstallin them.
 
You can not reverse their direction, the hole is a different size on each side of the caliper.
Smokey must have been confused when he posted that.

hy, is there a benefit to reversing their direction?

Opps, I editted my post. Guess I'm preoccupied with my new puppy Ozzy.
The pins must be tapped out of caliper from the outboard side of caliper, just enough so that you can pull it out from the "inside" of the caliper.

And reinstalled from the "inboard" side as there is only one way it'll go out, & one way it'll go back in, concerning removal & installation of the pin .

And..I'm referring to the pins on the REAR ATE calipers and what actually holds the pins in place in the caliper. IIRCC Girling rears are the same also?

If you'll look at the head of the ATE pins, you'll notice a small "pinch collar" underneath the "nailhead" of the pins

When you put them back in, from the inboard side of the caliper, it is best to tap the pin lightly with a small short or a very long drift & hammer, to fully seat it into it's hole.

This ensures that the pinch collar is in the caliper hole's seat for it fully and will not fall out.

That little "pinch collar" is what keeps it from falling out.

Maybe some of you have never noticed the pinch collar on the pins, I dunno.

BTW, you need to work on your communication skills & not be so rude. Learn some better language too.FWIW

Thanks, Smokey. I was having a hard time visualizing reversing direction of those pins, understanding the different dimensions at each end.

Hopefully this thread will help someone else with a search down the road.

Thanks guys,

Mel
 
I was watching over Ozzy, and also thinking "backasswards". LOL. Sometimes my "240 parts mental visualization" does not work as good as it used to, also
 
I believe that I just use a channel lock to press them back in tightly at the end. Seems to work

I use the punch as I have painted my calipers.No paint, no matter. Not sure how ya get a pair of Channel locs back there though.
 
Grab the caliper and seat one side of channel locks against "front" of caliper with rear of channel locks pressing in on pin, then squeeze..I used a punch as well to make sure they are flush..

They do have small split collars on them(the pins), if the collars are gone they need to be replaced.
Install ant vibe clip,then one pin , then other pin, then squeeze/press pins home..
 
Correct. I have seen them where rust has reduced the pinch collar's OD so much that they work their way back out also.

If I have one that works it's way out., I replace it ASAP.
