<p>Recently ran across these</p><p>And it got me wondering. How should I take care of my dust boot-less dynapros. How often should the be cleaned/rebuilt. How should I clean them when I swap pads and push the pistons back in.</p><p>Or should I just try and get some of the dust boot versions. Anyone have experience with them?</p><p>My car is definitely still a street car.</p><p>&nbsp;</p>

 

While I'm reading this on my phone, is there a significant price difference between the booted and non booted versions?

 

<p>About $20 a caliper.</p>

 

run the bootless and replace them every 3 years. they only cost 200 bucks for a pair. boots like to catch fire on track.

if the calipers where real expensive i would rebuild them. but for the sake of rebuilding a caliper for 60 or buying a new one for 100 bucks i'll spend the extra cash and have a body that isn't fatigued.

 

<p>Dynapros are more like 300. And if you can spend 340 and get more than a 10% increase in lifetime why not get the dustboot ones.</p><p>And suggestions on maintenance?&nbsp;</p>

dynapro 140 bucks.

if you track your car do no run dust boots. they catch on fire.

 

<p>http://www.summitracing.com/parts/wil-120-11481</p><p>50 dollars more total. If I get even another year without replacement aren't they worth it?</p><p>What is wrong with the dust-booted ones.</p>

 

with track use the dust boots catch on fire.

 

<p>Ok yeah. Thats a pretty good reason.</p><p>What about maintenance and cleaning?</p>

 

Just a random thought on my end, but even if you clean them, they're going to get covered in brake dust again in short order, right? You wouldn't be cleaning the inside, so I kinda doubt it would matter.

I would think the best maintenance would be to just flush the brake fluid to keep it clean/happy and inspect the pads. So say if you track the crap out of it one weekend, maybe flush the fluid after that for example and check the brake pads.

 

<p>My track pads dust, my street pads, not as much.</p><p>Also, dirt grime, etc. Brake cleaner?</p>

 

Did you fall and hit your head?

 

<p>No. He edited that post. When I saw his response all it said was. Both of them actually. He didn't say they catch on fire until I specifically asked what was wrong with them.</p><p>&quot;run the bootless and replace them every 3 years. they only cost 200 bucks for a pair.&quot;</p><p>Which tells me nothing of why not to, other than they are cheap.</p>

 

I would not spray brake cleaner on them. Just go find some rubber and spray it down with brake parts cleaner, watch it swell up big time and get really soft. That would be your O-rings inside the caliper if you spray them with brake parts cleaner.

 

<p>That is why I ask these questions instead of doing. Thank you.</p>

 

Are you actually just asking how to clean them to make them pretty? Or to improve reliability? I assume reliability. If you just want them to not look dusty, I'm sure soap/water is fine and shouldn't hurt anything. I wash the Brembo calipers on my C63 with car soap whenever I wash it, it's never hurt them. I'd be willing to be they have boots though, but i've never checked.

 

<p>Reliability. Grime around the pistons.</p><p>Street cars have dust boots for a reason.</p>

 

No worries. Brake parts cleaner is nasty stuff. I've had it take paint off before... I use it when building engines to final clean parts before assembly. Actually I rarely use it for brakes...

 

<p>I use it to clean my rotors from the oil they pack them with.</p><p>And washing my hands when they get real grimmy.</p>

 

Yeah but a street caliper with boots and regular fluid flush will last a very very long time. My 99 miata has all original calipers with ~160K miles on it, they work perfect. All I've ever done is grease the pins once when I bought it, and flush the fluid every year or two since. I would bet with no maintenance other than fluid flushes those calipers you run will work 3 years without an issue.

This is probably a dumb question, but can you buy calipers that have boots, and just remove the boots before a track day? Sorry, no experience with the calipers you're running so I dunno if this is possible, but perhaps?
