After installing noise insulation, you can install brake pipes and the entire brake system.
I bought all new clips, rubber plugs and fasteners for this.

New steel brake tubes with a polymer coating - the front ones are original, and the rear ones are an absolutely exact analogue of the Polish manufacturer WP. The thread on all tubes is M10, and the length of each is indicated in the ETK.

A set of reinforced brake hoses is also from the Polish manufacturer PHU Donocik Racing.
You also need a special key for bending pipes - without it, it would be difficult to bend steel pipes.


So, back to this section.
ЕТК_34_Тормозные механимы
In the first part, I already wrote about the installation of the hand brake, and in the second part, we will talk about the tubes and the hydraulic drive of the brakes for cars equipped with rear disc brakes and the ABS system.
Let's start with the front.
Brake pipe front

Front tubes:

Clip Visitor Messages in the diagram is no longer available to order, so I replaced it with a similar hose clip. I think it will be fine.
You need two hose clamps Forum for the front tubes, but you need 10 of them in total for the car - just like in the photo, there are 10 of them in the package.

The right front tube is fixed with three clips No. 6, which at the same time are the fastening of the sound insulation of the motor shield - I already wrote about this recently.


The tube exits into the arch through the rubber insert No. 3.

And it is fixed with a clamp to hose Forum

The same is true on the left side.
I fixed the left tube together with the right one with a Visitor Messages clip on the edge of the support. I'm not 100% sure that this was the case from the factory, but I can't see any other place for this clip.


Both front pipes go to the place of installation of the ABS hydraulic unit.

The rear pipes had to be bent into place, so for this, a vacuum booster with a brake master cylinder and an ABS hydraulic unit must first be installed.
Let's start with the ABS hydraulic unit.
ECU antiblock system

All brackets and bolts were galvanized, the body was cleaned and painted. The cover was painted by a specialist with texture paint for plastic - I liked the result.

I cleaned and treated the contacts of both relays with a contact spray, assembled the block, installed the fasteners.

The ABS hydroblock is ready for installation.




We screw the fasteners to the ABS electronic unit.



We install the ABS relay in place.


Clean contacts, ready to install. But after laying all the wiring.

We put the rubber cushions of the hydroblock and the "mass" bolt G104.

Insert the third pillow into the groove and fasten it. We also screw in the "mass" wire.

The ABS hydroblock is installed.
Next - a vacuum brake amplifier. I have written about him before. I was lucky enough to find a twin amp from an E30 325ix that becomes a bolt-on. But during the installation, some nuances were revealed - more on them later.Vacuum brake booster

Parts #7, 16, 17, 20 are not used.
The diagram shows a normal amplifier, so the photo below has parts that are not on the diagram. Namely - the original factory transition spacer with a gasket, thanks to which the double amplifier from the E32/E34 becomes a bolt-on E30.

Spacer from E30 325ix (35 21 1 155 135)

Another part missing from the diagram is the clip-bracket for the fuel hose (13 31 1 714 455). It's not relevant to this section, but it screws into the vacuum booster, so it's here.

Part No. 2 is an air filter that is no longer available for ordering. Judging by its remains, it is an ordinary paralon. I cut it according to the dimensions taken.

Rubber parts.

Double vacuum brake booster assembly.

I put the spacer on the thread sealant - that's how it was from the factory.

Next is the master brake cylinder.
Главный тормозной цилиндр/бахок


The brake master cylinder for the dual vacuum booster is different from the normal one. That is why detail No. 3 is missing in it. Also, the cover may not fit the wiring of the brake fluid level sensor. There are different connectors, but the covers can be replaced with each other. We install the tank and the lid - everything is simple.

It remains to screw the cylinder to the amplifier. Do not forget to put a new rubber ring between them.

We also do not forget about the bracket for the fuel hose - it can be seen in the photo.

Ready to install.

Of course, the vacuum amplifier is attached to the body together with the pedal unit, but there will be a separate section about it.
The amplifier is installed.


The next photo shows the same nuance that I wrote about at the beginning.

The double amplifier has a greater thickness than the usual one, in addition, thanks to the spacer, it has shifted significantly forward. And now, obviously, there will be some difficulties when installing the power steering tank - it will no longer fit into its place. It will be necessary to come up with something to fix it in place. But we will solve problems as they arise. Then we'll see...
And now that the ABS hydraulic unit and brake master cylinder are installed, you can bend and fit the brake pipes under them.
We start with the tubes of the ABS hydraulic block.
Brake pipe c ABS Pd

I kept my ABS pipes, they were in good condition. Just cleaned and painted them.

I ordered new plastic tube holders, but then it turned out that I had them all, so they did not fit.


We fit the tubes and connect the master brake cylinder to the ABS hydraulic unit.
On the cylinder, the front fitting is the outlet for the front brakes, the rear fitting is for the rear brakes.
The fittings on the ABS hydraulic unit have the following markings:
V - front entrance
H - rear entrance
l - exit in front of the left
r - exit in front of the right
h - rear exit
We screw the tubes and align them with plastic holders.


An analogue of the front tube holder that I mentioned earlier.

ABS tubes are installed.

It remains to install the rear tubes.
Brake drive pipe Zd

Parts Visitor Messages and Private Messages are not used. Judging by ETK, they are intended for machines with a maximum load of more than 1700 kg. I think we are talking about towing a large trailer, or carriage.
Brake force regulator No. 7 (34 34 1 156 716)

is placed after the master brake cylinder, and spacer No. 8 (34 32 1 156 869)

is attached instead of the usual brake force regulator No. 5 (34 33 1 152 494)

So, in my case, the usual brake force regulator is installed.
Rear tubes:

Clip Other Forums (34 32 1 158 467) on the diagram - I still did not understand where it can be placed. It is indicated that she is alone. But I had 5 clips on the bottom in the back. So I ordered it. But they did not fit at all in terms of fastening. It's good that my old clips remained intact - I put them in so that I wouldn't have to wait a few more weeks.
Clip Groups (34 30 1 161 567) is no longer available for ordering, but there is a substitute (34 32 6 855 500) - suitable. Only 4 pieces are needed, two for each rear lever.
No. 2 hose clamps are required for the rear tubes in total seven pieces.
Let's start with the installation of the brake force regulator. The bend of the tube here had to be made smaller. Then I will show why.

The brake pipe is laid along the bottom parallel to the fuel pipes and fastened together with them.
This mount is located in the fuel line section. Therefore, I will write about him later.

It's good that even though the fuel pipes are already bent from the factory, I bent the brake pipe along them. I will say that it is not very convenient to bend a 3-meter steel tube while lying under the car. Especially over the rear beam. By the way, this is where the clips that the new ones did not fit are put. The photo shows the old ones.



And here are the consequences of bending the tube, which I wrote about at the beginning. I made a very large bend on the brake force regulator and missed several centimeters of the tube to where the tee mounts. In addition, the tube itself was 3 cm shorter than the original. There was no desire to straighten and rebend the entire steel tube. I also didn't want to pass the clip over a shorter distance, so I made an extension bracket for attaching the tee. A little collective farm, but neat as it is)))

Further, from the tee to the left and right sides.

Left hose

Left lever - two clips.

The left hose is on the lever

Right hose

Right lever - two clips.

The right hose on the lever

So, all tubes and hydraulic brake actuator for cars equipped with rear disc brakes and ABS are installed.
It remains to install only the brake calipers. But first they need to be brought into proper shape. Therefore, I will write about it later, in the third part of this chapter.
