and front brake lines/flexi/caliper change.
---------------------------------------
Today I changed the front brake lines from Master cylinder to hose both sides. I knew I was going to have a job getting the old ones out so to make life easier I decided to change the flex hoses at the same time and whilst I was there I may as well change callipers for the ones I got off the bay. this is a bit photo heavy so will be done over several posts.
This was a relatively easy task to carry out.
Time taken about 5 hours but I was slacking a bit :P
Tools used:
Trolley Jack and 2 axle stands
Wheel nut wrench
Flat screwdriver
Cross head screwdriver
mole grips
wire brush
blow lamp
hacksaw
Spanners - 8mm, 10mm, 11mm, 14mm
Sockets - 10mm, 12mm, 14mm and 15mm
pipe cutter
pipe double flaring tool
bench vice
zip ties
So the first thing I did was slacken the wheel nuts and jack up support and remove the wheels.
Here is the drivers side before starting.
I put cling film over the MS to reduce the loss of fluid but it did not work lol.
Getting the pipe out of the union was a pain in the ass. I wasted 2 hours when I should of just taken a hacksaw to it as it was being binned anyway.
Next remove the U shaped spring clip, this will work lose quite easy with the help of some light taps and work with a screwdriver
Remove the connection at the Master Cylinder. (centre far left) 10mm spanner then just pull the pipe out from any plastic clips and lift away.
Actually its not that simple, due to the shape of the pipe and the need to keep it that way so you can use as template for the new pipe you actually need to twist and turn it this way and that to get it out.
Pipe removed
Flex hose removed, this took some getting out it was rusted in solid so a quick call to Craig for some tips and out with the hammer and mole grips and off it came. you need a 12 mm socket at the calliper end
Next up was to make my new brake line.
I took the old line and measured with some wire so I knew what length to cut.
The I took my roll of new pipe and cut the required length
I cleaned up the ends and added a very slight internal chamfer, then placed the pipe in the flaring vice ensuring the amount poking through was correct per the flaring die.
I lubricated the die with a little brake fluid and placed it into the pipe
Then I attached the compression tool and tightened up to make the first flare you cant really over tighten this as you can feel it when it is done.
I inspected the flare to make sure it was good enough to continue for the double flare, no point continuing if it was not the right shape.
The compression tool was used again but this time without the die to make the second flare completing the double flare.
On removal I had a nice even double flare, it was clean and true
I mated it up to a joint to check that it was good.
Then before repeating the process on the other end, I slid the couplings onto the pipe making sure they were the correct way round.
The finished pipe, now all I need to do is add the bends.
I found zip ties very handy whilst adding the bends as I was working by hand and just bending the pipe as I worked along the length I add ties as I progressed.
I then moved on to the passenger side, removal was just the same as I had done for the drivers for the most part, except this time I used a hacksaw on the pipe which saved me some time. Since this pipe is longer and very different from the drivers side here are pics. Also this pip runs along the bulkhead so you also need to pull the pipe away from its clip mountings you can remove 1 bolt and screw from the aircon pipe to make it easier. I also removed my air filter and heat shield to give better access.
Before cutting the new length.
New length cut and bent to shape.
I opted to do the flaring after bends this time, due to size and shape
And all fitted.
Passenger side complete
Drivers side complete
New pipes at the MS
And along the bulkhead
