Question [944 S2] Blue hose woes

Hello,

I've searched the forum and google extensively, but I couldn't find the answer to my question.

While pressure bleeding the clutch (one of the few things I had not done yet), I realized the blue hose was probably cracked somewhere as it's soaked (never happened after driving) near the fluid tank

wet end

dry end

I understand this is a specific DOT4 resistant hose
Looking at the PET, it's 27cm long


So sourcing it is not a problem.

My problem is;
How to I remove the crimp clamps without breaking the plastic tube (tank output / master cylinder input) ?

breaking one of these 2 is going to make a not-so-easy job both expensive and awfully more complicated.

thank you

I cut those type of bands with a Wizz-wheel and you can use a soldering gun to cut the hose by burning through the hose without putting any pressure on the tube.

insert a small flat screwdriver into the "hoop" of the clamp and twist, it should expand the clamp.
or you can get some strong side cutters to cut the clamp off.

As DHS suggests, a dremel tool with a composite wheel (whizzer) applied to the sticky-outy loop should do a neat, safe job. If you were less worried about the plastic nipples, diagonal cutters would be another option. Replacement Oetiker clamps can be had from Bel-metric.

It might be the angle of the picture, but I believe the nipple off the reservoir should be at a 90 degree angle. That may indicate you already have a cracked nipple.

Tough to tell in the above pic but there should be an elbow there, I think it's just the angle of the pic.
The real challenge is laying on your back with your head under the dash to release the clamp (part #24) and remove the pin (part #21) if you decide to replace the slave cylinder as a 'while you're in there'.
If you decide to go there, do yourself a favor and remove the drivers seat.

Not on the S2, it's angled

Good to know. When I redid the hose on my 968, I just sourced new clamps from Belmetric, and got a couple of meters of hose from Porsche. On the tip, another way of getting at the clip is to remove the fuse box from the engine compartment and access it from above. Still a PITA, but at least not working on your back.

I'm not replacing the master cylinder, just the hose (fingers crossed)

Ugh, next time I'll read the thread more completely, I was looking at the pic of the slave.

a dremel disc cutter to cut the clamp, a small stanley knife to cut away the fabric and expose the hose

it was indeed cracked and weeping, and upon gentle extraction, we can see it's badly frayed

DOT4 collection in a rag

I'm getting the new hose tomorrow so I plugged the tank output in the meantime

Thank you for your advice, it made the job a LOT easier
