Hello All:

I am ordering in parts to redo the front brakes on the '95 Max. After I pulled the Calipers, I check the bracket pins. One pin is the standard solid pin. The other has a rubber sleeve in a groove on the pin.

My question is: Does the pin with the rubber sleeve go in the top slot or the bottom?

What purpose does this rubber sleeve serve?

Anyone know?

Any help will be appreciated.

Thanks,
Mike

 

It's the upper pin that has the rubber sleeve on it. Check out www.motorvate.ca for some good pics. Don't know the exact purpose, but I ordered the front caliper rebuild kit that includes all the new rubber pieces and swapped them out.

 

Thanks. I had seen the page before. I will place them in the top slot.

Anyone have any ideas on there function?

Thanks,
Mike

 

There called caliper pins and they push the pads off of the rotors after you brake. This is so the pads dont drag on your rotors and burn up. Its a good idea to clean and regrease them during a brake job or if neccasary replace them.

 

Thanks for the reply.

I understand what the pins are for.

What I was asking (albeit in a poor manner) is what the purpose of the rubber on the top pin. I have seen many different floating caliper setups and none had a little rubber sleeve on one pin.

Any ideas?

Thanks,
Mike

 

I thought that was done by a square cut o-ring on the piston? And that the pins are for the caliper to slide on with floating/sliding setups. Also, I believe that there is some drag with pretty much all disc brake setups except for low drag brakes designed with dual diameter master cylinders?

 

Hmmm, both of my bolts have the rubber sleeve on them. I was looking yesterday while I had my wheel off.

 

I think, he means on the caliper pin itself, there is a rubber gasket on the upper caliper pin...I think this is separate from the rubber sleeves you are talking about which are on both pins on the outside where the pins meet the caliper braket...

 

As I recall, the rubber is just to prevent any water and dirt from getting anywhere near the actual part of the pin used in the braking system which operates under high temperatures...if any water got in there or dirt and took off the high temp lub. grease you'd be in trouble.

 

OK....

Sorry for the lack of good nomenclature.

I am not referencing the boot that surrounds the pins. These are for protection of the pins (i.e. keep out dirt, water, and/or other contaminants.) When I pulled the brake caliper the other day, I pulled the slide pins out of the caliper holder and one of the pins has a rubber sleeve on it. The other is smooth.

I am going to completely redo my brakes on Monday and I will get the digital camera out and take some pics.

Thanks for the help.

hello maxima peeps. Im working on a pals ride (1997 GLE) and came into a small problem:

i had to replace one of the rear caliper pins. in particular the upper pin with the little rubber bushing(Not dust/grime BOOT!). I have since discarded this broken bolt but the "caliper pin kit" i bought didn't have the little rubber bushing. Where can i find this part? do i really need it? can i fab something up?


anyone have some info about this issue?


thanks
Tim

 

The "pins" are called guide pins. And the rubber bushings are the guides for the pins. When you break, the rubber bushing actually slightly twist. I know for bmw, there is brass upgrade. Really nice but you have to reapply anti-seize compound every 4 to 6 months.

 

so my solution was to just use the 2 smooth steel pins without the grooves/rubber sleeves. I figured those may just help with vibration dampening or something. We'll see i guess. So far though it seems to be fine.

 

Keep us posted. I don't think that removing the part was a solution though. Just my thought..

 

I have just bought reman'd caliper brackets for all 4 brakes and one reman rear piston.

The rear piston came with "all hardware" and the guide pins it comes with consist of one solid one and one that takes the rubber bushing (which it came with ).

The pin kits I bought for the other 3 positions seem to conflict with what came with the rear making me wonder which is right (have not taken originals apart yet )

The H5075 kit (AZ) has one rubber bushing and one solid pin. Supposedly, this is for the front and the rubber bushing is the TOP pin I have read here.

The H15072 ones have no rubber bushing .. just 2 solid pins. Supposedly this is for the rear.

Why then did the reman advance piston I bought come with the version with one rubber bushing? Does it matter ? Did they just put the wrong one in there ?

Also.. off topic somewhat but I received 2x 14-1503 brackets for the the front.. but see on one web site there is a 14-1503 for the right side and 14-1505 for the left. (A1 Cardone pns)

I actually ordered the DORMAN 619504 which says they fit either side but got a1 cardones and it has 619504 and 14-1503 on the box.

Just hoping I don't have one of the wrong guys. Is the right side different from the left ?

Thanks a bunch..
