Not only do they stick all the time (And I re-grease mine every spring when I bring it out for the summer), but those stupid rubber bushing NEVER GO IN RIGHT!!!

Does anyone have an idea about any sort of easy way to keep the rubber boots from popping out when you are putting the slider back in??

I always manage to get mine in, but it can take me hours sometimes!

Any tips or hints for those stupis things would be greatly appreciated.

------------------

In all calipers the slides sticking is often the result of one or two things.

1. You or someone previous used the wrong lubricant. "Brake Grease" is the ONLY lubricant that should ever be used on them. If anything else was ever used then the bushings have to be replaced or they will keep sticking.

Additionally, brake grease doesn't wash off anywhere near as easy as oil based products often do. That means the system stays better lubricated. (It won't run at high temperature either.)

2. There is corrosion in the slide hole. Even tho the slides don't touch the walls of the holes... ALAWYS Grease the entire inside of the hole. That keeps water out and prevents corrosion.

Not sure if it will work for 88....

try using a deep well socket or a bit of pipe to work the boot back into the hole. Just don't use anything thin/sharp that mioght cut the rubber.

Ogre,

1. There are no rubber bushings to be affected by using the wrong grease. Only end seals, but I can see how a swollen seal could have the same effect.

2. The steel sliders are in direct contact with the aluminum caliper body.

AkursedX,
I feel your pain man. Those things are a ***** . You're not kidding when you say hours, are you? The only tip I can give you is to use good seals. If they are the least bit swollen or deformed, they are nearly impossible to get in. Oh, and use the method shown in the manual if you're not already.

Sorry... I had to go look the 88 up.... It's been awhile.

The seals can still make the piston bind if the wrong grease has been used. The oil can swell the rubber and make it sticky. This is a problem any time a rubber seal/bushing on a moving part is involved.

I would clean the slide and hole with brake cleaner or alcohol.

Lightly scrub inside the hole with some Scotch Bright or very fine sand paper if there is any corrosion. You don't want to change size/shape of the hole just knock out any trash.

Next get new seals and some brake grease. You don't need to get sloppy with brake grease. A little goes a long way.

put the whole mess back together. Lube the entire inside of the hole.

Put a film of grease on the slide before pushing it in. Push it most of the way thru but BEFORE you snap the boot on it, put a thin film on the area that just came thru the hole.

You want a thin film of brake grease on the entire slide between it's seal grooves.

Yes, there is a method for installing the seals. It's even covered in the Haynes book.

I redo mine every 6 months or so.

I did figure out an easy way to get the boots back on. Takes less than 5 minutes each slider now.

I could show you easily, but it's hard to explain. I'll give it a shot:

Start from the back of the caliper. Put the rear boot on the slider 1st, not in the caliper. Put the big opening of the boot over the end of the slider that will hold the bolt head and slide the boot along the slider to the other end until it is only hanging on the end by the small opening of the boot, but not far enough that the small end of the boot slips into the groove on the end of the slider. Now set the big opening of the boot into the hole in the caliper and carefully push the slider into the caliper from the back. As the slider goes into the caliper it will seat the inside boot.

Before you push the slider all the way through, seat the outer boot in the caliper. It goes in easy without the slider there yet. Once it's set in the groove, carefully continue to push the slider through being very careful not to unseat the outer boot as it crosses over the seat. Plenty of grease is key, and give the slider a little twisting motion as it slides.

Once you cross the threshold of the outer boot seat, continue to pull the slider toward you as far as it will go without popping it out of the inner caliper boot. Now the slider should be out enough to stretch the outer hole of the outer boot over the lip of the slider and then the slider can be moved back into place.

I don't know if I explained it clearly enough, but follow it as closely as you can. If you do it once, it's all gravy for the rest.
