Re: Brake lines-minimum bend radius?

Thought not, thanks for confirming. I guess I can't file the imperfections out?

Re: Brake lines-minimum bend radius?

Hello again all. Got the flares done by a local friendly garage. However, not too sure about a coupe of them. There is a bit of a ridge where the die blocks meet. What's the view? Are these useable? I'm a bit reticent to go back, as the guy did it while his boss wasn't looking, and I'm not sure I ca...

Re your picture of the pipe from the master cylinder:-

Make sure that the pipe is straight for at least an inch from where it exits the union nut before curving up and over the cross member. If it is not straight it can lead to stress and ultimate fracture/failure.
Ok, noted, will do. Thanks.

Re: Brake lines-minimum bend radius?

Final position of the new line from the master cylinder...... IMG_20200219_211706~2.jpg ..... And the new route between the clutch pedal. Compare with the photos I put up earlier in the thread, it's much better. IMG_20200219_211756~2.jpg I still have to get flares put on, so this is not the final fi...

Re: Brake lines-minimum bend radius?

I have made up new Kunifer pipes from the master cylinder to the servo, front 3 way union to rear flexible hose and the two pieces across the back axle. These last two were copper, the others were Kunifer, but I wasn't happy with the routing. All my brake lines are now Kunifer. In other news, after ...

Re: Brake lines-minimum bend radius?

Is it ok to re-use brake lines? The ones across the back axle are about 5 years old, copper, and look good. No obvious sign of stressing or cracking, the flares look good as well.

The brake pipe should go above the cross member and as Les says it should be sheathed in a split rubber sleeve to protect from chaffing.
See picture below.

Phil, have you got a servo fitted as well? There seems to be two pipes going over the cross member.

Re: Brake lines-minimum bend radius?

Ta. I thought it was best that way. I routed it through the cross member when I fitted the servo, but I've never been happy with the tight radius curve, and of course moving the cross member is more difficult. I've now got a new piece of Kunifer pipe in place, ready to cut the end to length and get ...

Re: Brake lines-minimum bend radius?

Hello hive mind. What is the opinion on the bend of this pipe? This is the feed from the master cylinder to the servo, in the engine bay. It isn't the original factory fitted pipe, I replaced it 5 years ago, when I fitted the servo and discs. Also, which way should it be routed? I have it going thro...

Re: Brake lines-minimum bend radius?

Ok, so I did what I said I wasn't going to do, and bought a brake pipe flaring tool from Halfords. Has anyone got any experience of these? Because, despite following the instructions to the letter, I haven't been able to get a decent flare in about 20 attempts, using a piece of old brake line. I'm c...

EDT treatment

Just had the modern, a 2005 Micra 1500 diesel, serviced at the local independent garage. For the 2nd time, they offered me EDT treatment, £99. For those who don't know, this is a power engine flush that claims to rid the engine of contaminants. I said no. What's the hive mind view on this stuff? My ...

Re: Brake lines-minimum bend radius?

The stack of washers is a good tip, thanks! The line from servo to rear axle t-piece failed shortly after I fitted discs. I was on the A420, just approaching the dual carriageway section immediately before the A34 at Oxford. Fortunately I was able to pull off, on to the uphill slip road, and brake u...

Re: Brake lines-minimum bend radius?

Hmm. Thanks for that insight Phil, I'll have to check the rear axle pipes. Is there a foolproof way of determining whether an old pipe is copper or kunifer?

Re: Brake lines-minimum bend radius?

Thanks for the link, though I have just this evening bought a roll of kunifer brake pipe from Frost's. I will trial fit it, cut it to length, then take it to my local garage to get the ends flared.

Re: Brake lines-minimum bend radius?

Thanks gents. I'm fairly happy to make larger radius bends by hand, but I was wondering what the smallest allowable is? I've seen somewhere that the smallest bend radius shouldn't be less than 3 x the outside dia. of the pipe, but I can't find that page now. I won't be flaring the ends myself, I'll ...

Brake lines-minimum bend radius?

Is there a minimum bend radius for brake lines? I'm replacing some of the brake lines, as I'm not happy with the run I put in some years ago, in particular the line from the 4 way Union at the front of the car to the rear. I have a servo, so getting the line into the chassis leg as originally fitted...

Re: Differential overhaul

Diff back in one piece now, planet wheel shaft locating pin (new, as is the shaft) in place and entry hole peened over. Diff ready to be fitted to the axle. Apart from renewing a couple of brake hoses, and rerouting the brake pipe from the master cylinder, and bleeding the brakes, it's ready for a t...

Re: Differential overhaul

Unable to edit the above post, so adding here that the oil seal is also fitted. I checked the pre-load again tonight, it is almost exactly 12in-lb.

Re: Differential overhaul

I have now got the pinion reassembled, with a 0.003" shim between the crush washer and the outer bearing. That has now enabled me to get the pinion pre-load up to around 13in-lb, but that is with dry bearings, and without the cage and crown wheel fitted. The pinion nut torque was slightly under 130l...

Re: Differential overhaul

As far as I can tell, the markings on the back of the crown wheel are 1055, and 008, both without a + or - sign in front of them. Photo below:- IMG_20200113_192808~3.jpg Does this mean 0.008" of backlash? If so, that's 0.208mm, and my measured value of between 0.2 & 0.3 mm isn't far out at all. Chee...
