How Common Are Brass Caliper Sleeves

Re: How Common Are Brass Caliper Sleeves

Joe,

I know the brass is somewhat soft. As I have gone back and taken a better look at them, one does need a little cleaning up, but the others seem to be just fine. There is one small area that needs a little dressing of some kind. However I dress it, I want to be consistent all the way around. At this point I think I will get it all cleaned up, then start with the lightest process I can come up with. I think it will be very minimal touch up to have it back to the way I want it.

If I run into any issues with it, I will be back here picking your brains so I do not do anything that causes me to have to re-sleeve it, again.

Wish me the best and I might have to not only have my fingers crossed, I might actually have to keep my eyes open when I do it.

With the advise you all have give me, I feel pretty confident that this should not turn into anything more than replacing the seals.

Thanks again for the advise and I surely let you know if I need a little direction.

i do not see why you wouldn't send the one in to be resleeved. however you try to dress the bore it will not be as good as a machined bore. as for brass being soft, i think that is a incorrect statement. many times i have seen steel shafting wear and the brass bushings are like new.

Jim, Paul,
Great piece of advice guys. It is something that I had considered before even starting this project, but after your recommendation and good results you seem to be having with it, silicone will go back into the system for sure.

I have heard many good things about silicone brake fluid, but did not realize the advantages were so superior.
Thanks for the input.

John,

First, I want to say that the flaw, in the one bore we are speaking of, is minimal. The only consideration was to make sure however I chose the clean it up, I did not create a bigger problem for myself.

If I thought, for a second, that it was not going to be 100% when I am done with it, I would send it in to have re-sleeved.

There were a number of people giving me their advice/opinion on this matter.
I think I know how to take care of it just fine, but a couple of the guys have given me food for thought. I am always open to whatever somebody else has to say, including you.

With my knowledge and the advice this group has given me, I am very confident the brakes will not only work fine, but I am sure they will stay that way for a while.

Some of the advice I was given on this thread lead me to do a little research on my own and I am very confident I can handle fixing the blem in the bore without a problem. But, you are right, if there is any question at all about the integrity of the caliper at assembly, it will be sent in for a re-sleeve for sure.

Hello;
Also consider following the Service Manual brake section referring to brake disc runout.
Improper disc dimensions will force the piston to pulsate forcing fluid paste the caliper piston seals.

On top of the lack of water absorbtion another advantage to DOT 5 (silicone brake fluid) is that it will not damage your paint. Glycol based brake fluid (DOT 3, 4 & 5.1) is some of the best paint remover known to man.

Ray,

To tell the truth, that was the biggest worry going into this. Three out of the rotors are just fine. I even oriented them to the spindle they were on so I was to be sure they on the exact same way they were before taking everything apart.

The last rotor is not really that bad. I have not had the time to rotate the rotor to see if I can get the run-out a little better. I have many extra suspension parts lying around here. Worse case,I may have to try one of those.

I have heard people talk about partial shims and a few other ideas that make me a little un-easy. At this point I am hoping the run-out is not going to be a huge issue. Keep my fingers crossed.

May I also suggest finding a shop with an "on the car" brake disc refacing system. They take hub inequities into account.

Ray,

I will take a look and see what I can find on the matter. At this point whatever it is I am doing to this car, I try to do it the best I can without altering the originality of the vehicle. Truth is, I do not know much about it either.
