General Replacing punto mk1 front brake hose

[whatleyt]

Hi there, I need to replacing my drivers side flexi brake hose.

I had a look at the weekend, I know I have to unscrew the union on the hardpipe part, and and remove the end from the caliper. But I can't see how to remove the actual flexi pipe from the mounting inside the arch!

Is there a trick to this, or a specific method to use, as it seems as if it is formed into the little metal bracket in the wheel arch.

Thanks in advance,

Thomas

There is a horseshoe clip holding it to the bracket.

Remember you will have to bleed the system so start Plus Gassing the bleed nipples every hour on the hour till the weekend.

If you haven't got Plus Gas, use Cillit Bang with bleach, the pre-mixed variety.

Cheers

most fun job of them all is replacing brake lines

If you can run to it, there are nice stainless nipples out there, not uber expensive. I treated my MR2 to a set when I put the Goodridge lines on. But plus gas (or GT 85) -- the other issue is snapping the hard lines while you're doing it -- a real pain.

brake pipes got messed up everytime when i was changing rear cylinder or front rubber hose = thats when the real fun begins, what else can u expect from a 20 year old car
just looking at the hoses wrong will puncture them

With GT 85 (or Plus Gas) I have a better than 80% success rate -- and the MR2 is 23 years old!

perhaps u have, perhaps

thread resurection from jan 2011 is this a record?
probably not

anyway remember to smack the bleed nipples with a hammer prior to trying to undo them as it loosens their grip in the fixing

i really dont see the point in using witches brews for hours before on these fixings because if these wonder fluids could get in then brake fluid could get out
remember its not the hitting but knowing what to hit that keeps us in employ

Not on the nipples, although I'd guess that a penetrating oil actually penetrates better than brake fluid (much thinner, designed for that purpose) and would remind you that the thread doesn't form part of the seal.

But on the flexi to hard pipe joints it's a godsend. the steel hard pipe tends to meld throughout to the steel nut.

I will leave the hammer to one Mr.Clarkson.

a hit with the hammer helps

message ends.............

cant undo the last nut on the brake line, how do i remove the plastic brake fluid reservoir, just lift it up?

 

[fingers99]

It sort of levers off -- a big screwdriver with some tape round the end or a prybar will help a lot. If you can get hold of one, an 11mm flare (or brake) spanner like this

helps not rounding the nut off.

 

[flisko]

i got a flare spanner and still rounded the nut off
should i just saw off the pipe and hit the nut with a hammer, if that would help

 

[fingers99]

You could try. But new master cylinders are very cheap -- I think the last one I bought cost £15 or so. So I'd not waste too much time and effort on it.

 

[flisko]

nah dont need new cylinder, just replacing brake pipes, gonna drill the madafaka tomorrow

 

[fingers99]

Your call, but I can't think of much that'll destroy the seals quicker than swarf.

What punto is that from? BTW got a quote for a new master cylinder for my punto, Best part of £100!!! The other one they listed for a mk1 punto was around £45.

Have you tried molegrips on it?

 

[flisko]

thats from a mk1, mhm havent thought of swarfs, will try to uncsrew with a plumbers wrench when i get the plastic off

This was for a Cinq. Still listed at £14.90. (eurocarcare.net). Can't find a Punto one on their site (ring Big Mick?) but Unto.pl list them at 107 zl which is about 21 of your English pounds.
Noddy --Where, in the name of God, are you buying your parts?

bolt was successfully unscrewed with a grip wrench
