Brake hose removal

Quote from: barchetta_ms on October 4, 2020, 14:47I ended up replacing the hard lines all the way from the ABS unit - not something I want to do when I do the rears.

Is cutting the hard line and putting a new nut on the end and then re-flaring the pipe an option?

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.

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

Benlake · November 3, 2020, 20:42

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

Benlake · November 4, 2020, 12:13

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?

AdamR28 · November 4, 2020, 12:14

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
