'Brake Pipes'

To be fair, if you bled it properly you've probably completely replaced the fluid in the lines from the reservoir anyway, at which point you may as well have replaced it with new fluid, rather than fluid that has been sat in the reservoir for god knows how long.

(Unless of course, it was recently changed, in which case - fair enough).

Only a couple of ft replaced, and the fluid was less than a month old. Total waste of time replacing it all.


Oh and Simon, of course you don't uncrimp it, that's absurd. Cut the crimped bit off, tends to be about the same length as the joiner fitting, bleed, job done.
 
After that silly post about not needing to replace fluid when fitting air filled pipes... Can we discuss the effect of brake pipe corrosion on brake pedal feel please ?
 
No ****in idea, was better after for me though. For all I know it just wasn't bled properly before, should have been though, a thorough job was done.
 
As a side note - I used to have issues with my the hydraulic clutch getting air in the system very, very slowly on my Corrado VR6 - the issue turned out to be the coiled hard line - I'm told its possible for them to go ever so slightly porous.
 
Nevermind, lol oops :p

It would have been the bleeding that made the difference, must have had air stuck in it. There's no way a corroded line can affect brake feel, to feel 'squishy' requires a reasonably large volume of fluid to be displaced, nowhere near what the 'flex' in a weak pipe could do.

I thought mine needed bleeding, turns out one of the fronts had a massive air bubble in it! Much better now :p

Cost will entirely depend on difficulty of the job, i,e do you need to drop the fuel tank to replace the lines. Materials are cheap, labour not so. I just replaced all the pipes on my girlfriends Corrado. They'll in theory never need doing again (Used Kunifer), so it's a worthwhile job in my eyes, and I know it's done.

Cling film over the reservoir is a neat trick, that I only learnt after I'd done it ;) Personally refuse to crimp any rubber hoses as I don't see it as being good for them.
 
I think its that most people if under the car getting dirty anyway, they'd go the extra 2 metres and change the fluid too, turn a cheap ***** job into a 'proper job'

Enjoy the vastly improved performance rather than slightly. And it wasn't the new pipe that improved the brakes, it was draining the crap from that one cylinder, so possibly front corner? A corroded pipe will perform exactly like a new one until it breaks.

Or you had crap brakes all round anyway?

Perhaps because some people like to look after their cars? If you got an advisory for a tyre that was just barely legal, are you the kind of person that would leave it for another year?

Clearly it's a different situation with Tyres, as to advise on tyres they must be close to legal limit.

And for every journey you do the Tyres are wearing more and more and likely hood is that if you do any reasonable amount of mileage then before the next MOT that tyre will become illegal to use anyway.

Where as the guideline on brake lines is interpreted by different testers in a different way, I must have about 4-5 MOT's done a week and sometimes I use different places when my regular place is too busy and every garages interpretation of what is and isn't an MOT fail with regards to brake lines is different.
 
I went to a garage where I know one of the mechanics and asked for a quote for replacing the brake lines. They said that the MOT tester who picked up on the corroded brake lines was being ridiculously picky and there was about 2mm of rust which they brushed off for me and then greased up. They said the pipes definitely didn't need to be replaced - which is good news I suppose!

You can't really be fussy with an advisory - he's done you a favour, as you've now taken measures to stop it getting worse.

Do you not read too well? Fluid was just weeks old anyway.

Next time I go though, i'll be sure to advise my mechanic who is highly qualified and has over 30 years experience that he hasn't got a clue and to take advice from an internet know-it-all instead.

cheers :)

will sleep better at night knowing that.

/edit, posting my first statement not seeing the 2nd pgage of the thread through, rolleyes at me indeed.
Still makes me think (through the application of science) that your brakes were duff initially, 30 years or not, he didn't get them right first time.

He didn't do them the first time.
