Miserable BC7 SUBARU!

An unexpected affair defeated me completely yesterday in spite of high score of daily luck by fortune teller, though the serious work on master cylinder cups replacement had been carried out!

Careful checking of removed rubber parts had no inconvenience like new after 150,000 km use, because the brake fluid had been replaced periodically for 20 years.
It's a matter for regret that BC7 must be used in healthy condition if I had not replace the inner parts of brake master cylinder.

Now, miserable BC7 is thrown away in disorder state with the 6 brake pipe lines opened.

There are three ways:

New replacement parts ordering to maker's depot at 176,000 yen.

Repair the parts mainly on O shape rubber rings replacement without no information nor parts supply by no one. Second handed parts from some junkyard may be possible.

Direct pipe lines connection utilizing modified proportioning control valves(two pieces). Checking for the necessity of the pressure control because of lack of ABS system, PCV as an alternative device?

I prefer the third choice, because of the elimination of heavy weight of ABS control unit and also direct pedal touch may be desired. But remember the ABS failure warning bulb in the meter cluster must be removed for annoying flashing.

In order to avoid the overpayment of Tax, I must spend some amount of income within this month.

2 personal computers for my business and for private use. 300,000 yen.

Digital SLR(Single Lens with Reflector) camera with 36by24 format C-MOS image element. 150,000 yen for Canon 5D Mk2.

Machinery replacement parts would cost about 400,000 yen for hoses with special couplers.

After some deeper consideration I would make a decision soon.
