Looking for some help!
I have some braided hoses to fit but Im a bit stuck getting my old ones off. I have managed to get one loose (the 10mm nut at the metal break line end) using wd and a flared spanner but the spanner keeps slipping on the other ones. Is there a handy trick anyone happens to know?
Thanks
By 'flared spanner' do you mean one of these?:

Yep thats the one I just and bought a 9mm one to see if I could a tighter fit but its too small the 10mm feels a little loose, which is why it keeps slipping.
Im thinking drastic measures might be needed :(
3/8" imperial is just a nadger smaller than 10mm -if you can get one.
@Carolyn ' s spanner is Imperial , you have Metric, there maybe a slight difference. But, as you are removing the brake hoses and if the " open ended" spanner is not working for you, you could try cutting the hose so that you can use a ring spanner or better still a long reach socket with six points. This will be messy so be prepared to catch the old fluid in a tray.
PS, Carolyn's "try an Imperial spanner" is far less drastic, so try that first!
Ok thanks I will try the 3/8 spanner first and if that doesn't work it will have get ugly!
If you don't have any plan to reuse it, use a pipe wrench

There's ugly , then there's a pipe wrench.😉
Haha starting to wish Id left them alone :(
I think the little nut might be needed the goodridge hoses only seem to have a thread at the end.
Why couldn't the other 3 nuts be more like my little buddy on passenger side front.
Holy thread hijack :)
I have some of these to fit too, and I've asked on here about these clips before but got no answer.
Does anyone have the foggiest what I do with these little things..

I completely fubar'ed my front brake hard lines when doing this - I ended up replacing the hard lines all the way from the ABS unit - not something I want to do when I do the rears. I started with a flared spanner and ended up with a pipe wrench and a knackered nut on the on brake line. I think the age of the car and the fact it had probably never been undone doesn't help.
Watching this with interest to see what other suggestions come up. Is cutting the hard line and putting a new nut on the end and then re-flaring the pipe an option?

They look like they can be fitted after the hoses are installed. There are 8 of them for 4 hoses , so 2 for each hose. They must be to locate/ limit the movement of the hose relative to some bracket or other.
Someone might now take pity and come up with an experience base answer.

You could have "that" parked over your 2, it would keep the rain off!

Re-flaring a line in situ would be difficult/ impossible, but would also mean that the line would be shorter which may be then difficult to get into the same position.
Some things on our cars are unfortunately due for replacement now because of TMB.

That was my hunch too actually. Wasn't sure which bracket to fit them around. Makes sense to not have them moving around in the brackets too much.
If the 3/8 flares spanner won't get it could it carefully be cut with dremmel and pried off - risk might be ending up with a mangled thread. The other risky option I was thinking was blow torch maybe if the line was drained from the caliper end.

Heat Gun ?
Yeah there is a risk I blow myself and the car up though!
The nuts on the hard brake lines for cars (particularly Toyotas) of a certain are are problematic. I learned this many years ago.
I now would never use open spanners (including flared spanners) unless I can be certain they will undo. I go straight for locking pliers. This avoids most rounding-over issues. Granted a couple of the flats will be marred but doing this first ensures a solid purchase for the jaws of the pliers.
When I bought my MR2 in 2014 the pipework was in excellent condition being a 2006 car - I therefore undid all four corners then using a flared spanner to avoid future problems. I've repeated this every year or so since to prevent the inevitable should I need or choose to swap out the flexis.

Having reviewed the situation, and no other input! maybe the item that these clips locate is the black "bracket" on the hose.
As previously, the clips go around the hose and it may well become intuitive once you offer the hose up to position it.
Yeah I would say they locate the black brackets, and the black brackets are bolted to the damper. Will be obvious once you start the job!
Like this right?

I haven't even looked near these on my Roadster but the older Starlets I have there's been quite a few similar issues. I cut the rear hard lines back to a suitable spot, used the cut off sections as templates to make new ones then added a union so as I could replace the affected length of pipe in one piece.
You need a roll of fresh pipe, brake line cutter, hand held flaring tool, couple of small files, some cable ties and a lot of swear words but it is possible. Getting the flare right whilst lying under the car is tricky but if it was easy it wouldn't such fun eh?
EDIT: Used this sort of join to connect the new section to the old pipe:

Hope that helps explain it better.

That's as I envisage. Don't fix the clips until the hose and bracket are installed. I believe the clips limit or restrict the movement of the hose through the bracket, relatively straightforward to position on the rear. On the front, of course, the caliper moves with the road wheel so I would turn the wheel lock to lock to see what is happening and fix the clips accordingly.
@Benlake I do hope you've been making good progress while we've been busy hi jacking!
It's not too bad to redo the front lines in kunifer/copper (and I speak as a complete amateur) but you will want one of the decent £30 hand flaring tools rather than the cheap crap bars that come with the kits.
On the other hand, complete lines really weren't that expensive direct from Toyota when I looked, but there was a bit of a wait to get them delivered.
I am eagerly awaiting my 3/8s flared spanner maybe it will come tomorrow, I will try it out. I ve been squirting more wd on them. If it starts rounding Ill stop and get the pipe wrench out.

WD?
Wouldn't plus gas be better?
I just bought wd rust penetrating stuff but will try it out - need all the help I can get.
Try a 50:50 mix of acetone and ATF, shaken in a spray bottle to mix, then squirted onto a joint that has been heated with a blowtorch. Sounds daft but Google it - works amazingly well.

Just don't forget your PPE.
And toffee apple ;)
Well that didn't go to plan, got the bolt free on the other front pipe but its still somehow stuck to the hose, the rears aren't going anywhere. I think its time for new brake lines the fronts will disconnect ok. Looks like you need to drop the petrol tank to get at the rear union where they attach :(
Well petrol tank is on the garage floor and I have shiny new brake lines finally, this will be a good little lock down project. I didn't fancy doing it myself with the copper ones with it been a track car I'll pay more for peace of mind.
:) just for info.
i recenly had a garage do this with other work and they gave me the car back with N/S/Rear to do. they did try but there was no movent and did not want the stuck at his place.
hopefully next week he will be haveing the back car to finish this off and he has everything ready to even make a new line as well if needed.
I do no of othes on here who have done this job and always find 1 of them is realy hard to do
Yeah it looked so simple two bolts and shiny new hoses! I spent 150 with mr2-ben for all 4 hard lines, Id be interested to know what a garage change for making up new ones?
Crikey. Think I'd have gone copper tbh, and just route them somewhere out of harm's way.
We managed to fit the new Toyota brake hard lines and finally the goodridge hoses. For anyone interested the procedure for the rears involved removing fuel pump and petrol tank. This allows access to the unions which sit above the tank. Then a fair bit of wiggling and jiggling. The fronts were much more straight forward. At 157 quid for the hard lines as others have said not a very cheap option, but it worked.
Can now start planning some track days for spring :)
