Stahlbus speed bleeder valves

[MLB]

Anyone got any experience with these?

Stahlbus Speed Bleeder Valve

Brake fluid is a safety-relevant wear part…a fact few people are aware of! Old fluid can become compressed and cause brake fade or even failure, fresh fluid maintains the pressure and keeps the brake system operating effectively. Brake fluid is as essential a component as the pad, discs or...

The bleed valves on my brembo calipers have started weeping on track, probably due to opening and closing too often.

I'm having them refurbished and would like to avoid this happening again, would these speed bleeder valves work on track?

Only reservation I've got is that they seem to stick out a bit more which might make them vulnerable to snapping off if a stone hits them?

A bit like the Stahlbus oild drain valve, looks good but without an undertray I'm not sure I'd like it sticking out that much.

I feel like I've seen Darkside using these before. Maybe a member on here too

Can't comment on them myself but deffo something I'm gonna follow

 

[Mr Underhill]

I'm sure @Tomotek has something similar to these on his Race car.

 

[MLB]

I've sent a message to demontweeks and Max at M.S. Custom Engineering (where my brakes are now). See what they come back with.

@frayz I seem to remember you were quite happy with the Stahlbus oil drain valve, have you given these any consideration?

 

[JAParker]

They are very common in the bike world, I wouldn't have any issues with running them in regards to confidence.

 

[Louis]

I was going to get these but decided I'm too tight to spend £80 on bleed nipples.

That's were I've found them, my brother mentioned a lot of his friends have them on their bikes.

@Louis agreed, they are expensive but if I'm messing up my bleed valves again and need them refurbed I'd rather spend the 80 quid. And it makes for easier bleeding apparently, saves getting out the eezi bleed on trackdays.

If you use a really good fluid like Castrol super response then you won't be needing to bleed them as much, fantastic but pricey stuff

 

[MLB]

Is that Castrol SRF?

I was thinking of at least going to RBF 600 from ATE typ200.

 

[frayz]

I use Castrol SRF in both the Clio and Cayman, great stuff.
My oil check valve has been good so far.

Yeah, typ200 isn't much better than standard stuff ime. Rbf would last a couple of track days and srf will last a season of racing with only about 50ml taken out the calipers which made no difference

You have the Goodridge speed bleeders and they are leaking?

Stahlbus Oil Drain Valve

These oil drain valves are an ingenious new system from Stahlbus and have been developed so you can perform an oil change completely safe and clean - no more hot oil to contend with or dropping the sump plug in your drain tub.Makes oil changes cleaner and fuss freeReduces the risk of hot oil...

looks like a game changer!

If I was rebuilding calipers MLB I would 100% go for the speed bleeders - I hate bleeding brakes and that makes it look dead easy.

Well at least that's going on the list for when the calipers get back👍

Standard valves are leaking, looks like marring on the surface where the bleed valve sits in the caliper. Goodridge speed bleeder still need tightening in the caliper. But they do look good as well I have to admit, super easy and if upgraded fluid means less bleeding they would be a good alternative.

Have you used the Goodridge ones?

That's the oil drain valve, nearly bought that but think it would stick out too much from the oil sump.

Same for the speed bleeder, seem to be a good bit of kit and make bleeding brakes dead easy, but I'm afraid it'll stick out a bit too much?

Better fluid and the Goodridge ones might be an even better option.

Maybe, I think some people fit sump oil temp senders which stick out quite a long way so its probably ok?

The goodeidge nipples are half the price too, my only concern would be air getting up the threads while you are bleeding the brakes while the Stahlbus ones solve that issue nicely. Are you on 15" wheels?

 

[MLB]

Not yet, having the calipers machined for PMS brackets as part of the refurb and looking at 15" wheels for track. Does mean I can't test fit..

I've read some reviews and they did mention air getting in through the threads which should be avoided by a special coating on the threads which will need to be reapplied regularly. Someone suggested they Teflon taped them all 🙄

Anyone know what thread length the 197 Brembo bleed nipples are?

Yea I have the Goodridge ones and they seem to work well. Same size as a stock nipple so you're not worried about them catching.

 

[MLB]

And they don't leak around the threads while bleeding I assume? What fluid do you use? For track as well?

I'll have the calipers back next week and will measure how much clearance I've got. Demon Tweeks came back with 30-35mm out of the caliper.

According to stahlbus Clio 197 calipers need m10x1 20mm valves, but they also say that's for TRW calipers, they are Brembo made aren't they?

Rob,

I run a full PMS sump guard that I still had to modify to house the drain plug. I wouldn’t fancy running one without a guard covering it.

 

[MLB]

Looking at the scratches on your sump guard I wouldn't either 😂

Mine bring as low as it is I'd be afraid of it dropping its oil every drive..

 

[frayz]

I live in an area where I drive a lot of undulating lanes every day. So a sump guard was always up there as an addition to when I lowered it. Same reason I removed my genuine cup splitter… it was only a matter of time. 😅

 

[PhillipM]

I teflon all my bleed nipples when I refurb calipers tbh, makes bleeding way easier. Never used the speedbleeders though as I vacuum bleed everything anyway - I just fit the 2-piece wilwood valves to everything and anything that has damaged seats.

That is close!

Superb attention detail as always frayz!

 

[frayz]

I’ve since had some alloy pucks turned up and welded onto my sump guard to shim it down about another 10mm. This gives a nice layer of protection that I’m sure will be fine for road use. I wouldn’t run the plug valve for stage rally use.

 

[R3k1355]

And they don't leak around the threads while bleeding I assume?

No not at all, and I ended up bleeding them quite a few times over chasing some air trapped in the ABS.
Slathered them in red grease once to double check they weren't leaking and all were perfect after multiple uses.

What fluid do you use?

Just regular DOT4
