Had my annual service this week, and amongst other things I asked the garage to look at the brakes as it felt to me as if they were just starting to warp.

During the mechanic's test drive my front offside Goodridge braided brake pipe burst :eek: Apparently the pipes are connected to the diagonally opposite wheel, meaning there was no braking to the offside front wheel and nearside rear wheel. Thankfully the mechanic tested the brakes on a straight rather than a bend, and thankfully there was no accident or damage to car or driver. The garage (Alfa specialist) have explained that on the front the brake pipe has to do a sharp 90 degree bend, and the braided hose had frayed and burst at that point.

Under his advice standard pipes have been fitted top the front now, with braided left at the back as there are no sharp bends on the pipes back there.

I'd now strongly recommend any GTV owner with braided hoses to inspect them ASAP and to plan to change them regularly if they want to stick with braided hoses.

FYI, my pipes have been on for 4 years and 20k miles.

Interesting report Markos, pleased that nothing nasty occurred.

Does make you wonder about mods to cars in general though doesn't it. Maybe the original designers got it right in the first place ?

As you know I'm not convinced about Powerflexing suspension bushes, another common mod on the 916's.

Running for cover now............:eek:

How come there is a sharp 90 degree bend? I have braided hoses on my 156 and there are no sharp bends, only a very loose 90 degree bend coming off the union with the solid pipe.. I would have thought the set-up was very similar on a GTV. Any chance of some pictures with the wheel off?

Dunno mate, hopefully someone more technical can help. Someone must have a pic lying around?

.....and therein lies your answer. What's missing in the shot of the old and new hose compared? You need to transfer the plastic rings over from the old hose. These, positioned correctly, stop the hose rubbing on the bodywork with the suspension travel. No, they are not the same diameter, you have to improvise.

Good spot Watshot, I think you're right.

It's not me asking the question:)
You are right ofcourse, those distance rings are a must, i have mounted them later on, when i found some thin rubber hose for braided lines so the diameter was right and plastic rings are in place.
Well done Alan, sounds like everyone with braided hoses on a GTV ought to get these 'spacer' rings to stop the braided hoses wearing away when they touch the bodywork. My previous mechanic should have advised me on this or sorted something himself when he fitted them in 2005.

That's interesting to say the least. My Goodridge hoses have been on for 7 years now and 60k miles. Time I checked them I think. I regularly brake down hard from about 80-90mph and so far all good, but now I am paranoid.

yeah off you go now.....before i start on you:tut:
:lol:

powerflexing is an absoluultely immense mod to make


ive actually been told a couple of times by 2 different alfa garages about modding GTV's and to be careful as possible, brakes and air system being the most delicate to touch, so im not suprised about this brake hose issue.....glad you discovered it and all is good....a lesson for all that sometimes it pays to just leave it alone.....

unless your gtv doesnt have a spoiler of course...:thumbs:

Thanks for the warning. I'm about to do both cars with Goodridge hoses but I might rethink the GTV now. Glad I only have the 164 set bought and not the GTV yet!

*WHISPERS
Hi Nige,
I powerflexed my old GTV V6 - if you can afford to not do it then don't! Thats my advice matey :) Powerflex are great for the money, a nightmare to fit and then you will have to pay more to get the fillings in your teeth sorted :lol: Also they do remove the slight passive rear steering that you get in the normal bush set-up ;):thumbs:
