Not without the invaluable help I get from here.
You warned me about lower grade bolts and I found one 8.8 used in one of the caliper pins.
I don't know if you can see it from the picture but it's very slightly bent!
So it's very important to use proper bolts!
I mentioned M10x45 bolts before for the caliper carrier but it's not the right size.
Correct size is M10x28 for >93+ models. I read the wrong size from size from catalog. Please be informed.
I had to cut the bolts for the carrier but I know the heat generated when cutting the bolts is not good. So I'll buy and replace the bolts with the proper size. It's very easy.
For future readers, here are some extra notes about the work:
First of all, the brakes are important for your own life and the other people. So if you have any doubt, don't attempt to this work yourself.
I used a torque wrench for critical bolts like stub axle, caliper carrier etc. I recommend using a torque wrench.
I used thread locker liquid on critical bolts that will endure heat. Like caliper carrier and caliper pins' bolts.
Do not, never ever attempt to do this job with an open ended spanner on solid lines' unions. You WILL strip them! 100% guaranteed.
This will render the car unable to move. The damage could be repaired only by a brake specialist with brake line building tools so you will be in a sh...ty situation.
Buy this spanner. You won't regret it.
It is called brake line spanner. The size is 11.
On the flex hose side I tried using open ended spanner first but when it felt like it's about to strip, I used a ring spanner.
If you can't insert it from one end you can always cut the old hose. You will trash it anyway.
Deal with the spilled brake fluid.
Brake fluid WILL KILL your paint work! Don't touch the car with brake fluid spillage on your fingers.
Even one tiny drop of brake fluid will damage the paint!
Removing the brake union spring clips may be hard. They could be rust-seized or they could have small stones stuck beneath them. They could have been painted with anti-corrosion stuff.
I used this method to remove them:
If you remove the union first, it will be easier.
To remove retaining clip, I used WD40 to lubricate the hollow between the clip and the body extension. Then I tried to insert a small screwdriver between the flex hose head and the retaining clip. I used a hammer to gently tap to the screwdriver.
If it's not moving, try this:
Add more WD40 and gently squeeze and release, squeeze and release. Your Aim here is to help WD40 find its way inside.
After that, I tried to tap the screw driver into that location before and it moved the clip outwards.
I continued with a larger screw driver that I could turn after tapping it between the clip and the hose's head. After moving it enough with help of the screwdriver you can pull the rest with pliers.
I used Bosch Superfit to lubricate the caliper pins, piston/brake pad touch surface, front brake pad side friction points and rear brake pad side friction points.
For anyone who needs the correct size for the rear drum gasket this is the size: 40 . 52/58 . 7.5/01
