Nicely done Tony, I hope you get an answer to those problems! JIM
Brake upgrade.
- Thread starter t-tony
- Start date
Great write up Tony and great improvisation.
Seems worth a bit of agro for improvement in braking performance,they look very trick too

They are available in a large range of colours too Steve, I can certainly feel an improvement just with the fronts, mind you that's where most of the braking is done after all. Dead easy job took me about an hour and that included ferking around with those washers too. The rear ones will be reasonably easy too, I just want to know if that is what you're supposed to do and if it is they should bloody well tell you.Great write up Tony and great improvisation.

I could've got it finished today then.Tony.
Your not old mate just mature
Yes you would think there would be some guidance included in the pack with some pictures to help.They are available in a large range of colours too Steve, I can certainly feel an improvement just with the fronts, mind you that's where most of the braking is done after all.

Last weekend I sent an email to the supplier of my braided hoses and duly got a reply on Monday.
I am sorry there was these issues with your hoses.
We do a different female fitting for some of the other BMW models and that would have been better suited, so I will have the specs changed.
I got the specs for this vehicle from HEL performance, so tomorrow I will speck to them to why they choose that rear setup.
We don't make replacement hard-lines so I can only imagine the specs where designed to remove the hard line between the 2 hoses and to reuse the existing bracket.
I am more then happy to send you some replacements with the different fittings should your wish? I would just need to find out more about these rear specs first.
I apologise for the inconvenience this has caused you.

Liam
For someone with a British sounding name he does seem to have a problem with the language (or keyboards), anyway a pleasant enough reply so I told him I would persevere and then send him pictures of the hoses fitted and what I needed to do to make them fit.
I also told him that more info was needed in the information leaflet to clarify that this kit deletes the short steel pipe between the 2 rear hoses.
Below is the old set up next to the new 2 hose arrangement.
Apart from the large washers required as were also on the fronts, the only other problem was the male union at the centre joint was too long to keep any pressure on the mounting bridge at the joint. It would have been loose at the bracket (hope that makes sense)
So what I did was make two "nuts" to screw onto the male unions and tighten up to the union head as below.
I made these nuts by getting a joining union and placing a male union in each end to keep the shape when tightened in the vice, this also preserves the thread too, I cut two pieces off and fitted to hose union as shown.
After placing the pedal bar on the brake pedal (this moves the piston in the Master Cylinder and prevents fluid running into the cylinder and eventually out of the system when you disconnect a pipe or hose).
With this in place you can remove a pipe, hose, bleed screw, whatever, and all you will lose is a tiny amount of fluid due to the pressure in the system but nothing after that.
After fitting the new hose set up I removed the pedal bar and bled the system on the O/S/R and checked for leaks under pressure.
Where the old Flexible hose was anchored to the rear suspension arm at the joint of the steel pipe I cut some rubber hose and packed it around the new hose to allow it to be clamped back in place. See the first of these 4 pictures.
Same operations on the N/S/R
Wheels on (130NM) and a short road test out in the foggy evening gloom. Brake pedal so firm now, looking forwards to the next part of the upgrades probably just after Christmas if Shirl gets all the hints!
Tony.
ps. If you have any questions please ask.

Top job mate and even more inginuity,worth doing if it's improved an already good breaking performance.
Steve
You can try it next Saturday mate and see what you think.

Top effort Tony, clearly a man who knows what he is doing.
Nothing like a decent set of brakes to give you confidence

Hi Brian, he did say that there was an alternative union but unless he gets feedback he won't know to do anything about the problems. Hopefully I'm giving him a heads up on how to improve his items. The general quality of the hoses does feel good I have to say so it didn't really take me much longer than it should. I did both the rears in 1 1/4 hrs this afternoon (inc. tea break
)Tony.
Cheers for that mate, this is the type of work I enjoy Andy, finding a way round a problem and making things generally. Modern day car electronics bore me to death. No interest in that side of my job at all.
Tony.
I couldn't see the need for a join either mate but it does allow the use of the original mounting bracket I suppose to keep the hose well away from the driveshaft.
Tony.
