Do Metal Caliper Guide bushings really help?

Backstory
I did a brake job on my e39 m5, I couldn't get the passenger side caliper to go back in. It took me an hour with some extra leverage to barely push it back in. It clearly needed to be rebuilt. I got a deal with a local company to rebuild my front calipers for $35 a piece. Including new pistons and boring out the old hole.

The question
Do metal caliper guide bushing actually help improve braking? I am already replacing the hoses with stainless steel hoses. So why not go all out and buy metal caliper guides. They claim

They must be periodically removed, cleaned, and relubed. Else, they'll stick.

Some here say they are not worth the trouble.

I wouldn't bother with them. I just use Neverseez in the pins and for the last 18 years, all has been fine. Yes I know that they say they shouldn't be lubed.

they need to be lubed way more often than your going to want to take it apart.

screw it then, my brakes seem fine. FWIW, I put anti-seize on my guides with the rubber bushings.

Also is $35 a good price for having my calipers rebuilt?

You're using different words, so, I'm not sure whether this thread is on the same topic or not, so I post it here, for the OP to determine.
- Are brass caliper slide pin bushings better than rubber bushings in the brake caliper rebuild process (1)

edjack - how frequently do they need to be relubed? Would once a year for a car that is driven 10K miles a year be enough or more frequently? I bought SS lines and was planning on doing the bushings and rebuilding the calipers at the same time because the calipers would be out and apart anyway.

Do you or anyone else that has actually made the change think it is a worthwhile change. We aren't talking about a lot of money.

edjack doesn't know.. cause he doesn't have them... They don't have to be lubed at all.. AS i said several times.. The lube picks on debree which shortens there life and makes it difficult to remove them in the future,

ask me how i know? i have 4 sets and a set on the shelf

but if its a specific answer your looking for,
*yes once a year for a car being driven 10k would be fine,


Disclamer : you wasted your money on SS lines,


Like i said... 4 cars 5 sets (Ive got 20 bushing sets )

further more...

I would never even install a caliber with out them anymore... there is ZERO point of useing the old 1980's style bmw bushing

they are also universal they will fit on every model of bmw between the late 70's to current

(it might have be like 81 or 82 actually)

Thanks for response

If no lube what does annual maintenance include - carb cleaner and a little lite sanding?

Yes, that was confusing.

They don't need to be lubed. Once a year. Which is it?

Im sorry guys.. Im tired and i really cant repeat my self on this again and again, This is something you either want to try or dont... its 40 bucks.

this is the bottom line, take it or leave

they will prolong the life of your pads they will give you a better more even braking across the board, and if you use them in conjunction with cross drilled rotors will give you a ez Ten fold better stoping..

I can lead you to water but i cant make you drink....
