Goodridge Braided lines

These braided lines for the Z4M substitute for the whole section of rear line from the wheel arch to the caliper (inner & outer hose and tiny section of pipe between them). They use the OEM brackets and clamps. Fitted well on my car:

In fact, I do now have a braided clutch hose and deleted CDV.

On opening the original package of brake lines, I was was surprised to find a solitary hose in there, which had been sent in error. After looking it up and discovering it was a clutch hose, I decided to buy and keep it and get that fitted at the same time. It doesn't stop the kangarooing at lowish revs in low gear when cold, but does get rid of a lot of the awkwardness in releasing the clutch. I expect this is down to the CDV removal, as I haven't been able to really test the benefit of the clutch hose yet.

Back to the Goodridge hoses, I can give credit to CA International for sorting things out quickly and making sure the brake hoses reached the garage in time.

The Goodridge stainless braided brake hoses for my Z4MC from CA Automotive have just 4 parts and they match up perfectly to the metal pipework at the obvious junctions.

I'm presuming that you're suggesting that the rear brake pipes should have an additional pair of braided hoses? I've read elsewhere that the inner pair of OEM flexible hoses are actually braided.

i did away with that myth after i cut my stock units up....

they are rubber.

Was there any fibre reinforcement in the rubber?

It had something in ther but it wasn't metal braided. Like another harder plastic/rubber.
 
Talk to Ben at Hel performance as long as you know the thread sizes they will knock up a set in no time
i had an 18" line made and delivered for £25 he even replaced it at no cost when i messed up the thread dimensions

Which will expand when the pressure goes through it. Steel braided line won't - or shouldn't under the pressures applied through breaking! Spoke to Hel through my contacts on the MLR and have got the clutch hose on its way :) Best of both worlds then
 
im just repeating what ap told me about the 2 rear smaller inner hoses. FYI i have ALL braided lines on this car. im just letting people know ap told me its not worth it in the case of the 2 inner ones.
 
I know this about //M's but ...

I have a 3.0 and changed my hoses to braided SS at the weekend on the rears it sounds like the same as your there are two sets of hoses,

I ordered a HEL kit from cam skill and recived only 4 hoses in the kit that was advertised as being a complete kit for my vehicle

I personally dont see the point of changing 1 out of 2 rubber hoses to ss

That's the sales pitch. Fibre reinforced rubber hoses expand very little.

Steel braided hoses are often just dress up parts.

Has anyone noticed a tangible benefit from braided hoses on the z4m?

i have ALL braided lines, including the clutch..... honestly.... i didnt notice any difference at all.
 
I noticed a different feel to the pedal on my e34 M5, but that had 10 year old rubber hoses on it, so even new OEM ones would have felt different :P

Only went for the (6-piece for the M5) Goodridge ones because they were no more expensive than OEM, and they'd just brought out the low maintenance, silicon-covered, multi-colour range.

Not in the z4, but my evo's had them replaced with braided lines and it always made a difference. They felt more progressive when warner. You only need slight expansion in a pipe to feel a difference.
 
Why would a clutch line make a difference? the slight expansion of a rubber line won’t make a lot of difference will it? I can see it on brakes where you are pushing against a solid object and the more of the effort you can direct to the piston the better the brakes, a clutch is either open or closed I just don’t see the benefit
That said if I was replacing a worn rubber hose i would install the stainless just because it will last longer and looks better.

the clutch/brake is the same circuit.... the reasoning behind replacing it is to remove ALL the rubber from the circuit, i only swapped the clutch line as i put alittle to much pressure on the rubber one during the CDV removal, it looked mishapen so i added a braided unit.... i felt no difference what so-ever.

The only shared component between the clutch and brake hydraulics is the reservoir. It has a partition in it so that complete loss of fluid on the clutch side won't completely drain the fluid in the reservoir on the brake side.
