Brake master cylinder replaced

Time to get the Saab 900 T8 Special out of the garage (it hasn’t been driven in 6 months…). There’s a Saab Club spring event a week from now so I need to fix a few things and get it on the road:

I had to change the brake master cylinder. I got a good replacement from the spare parts car – so I decided to use it rather than buy a new one (even though they are pretty cheap).

Changing the master cylinder on the 900 is easy, just a few bolts – but bleeding the brakes afterwards turned out to be a bit tricky.

Bleeding the brakes

Only two of the four calipers could be bled with the vacuum pump – somebody had broken off the other bleedscrews on the two other calipers!

Actually it took quite a lot of persuation to get the two intact screws open but I finally succeeded. The other two calipers had to be bled from the brakeline nuts.

New calipers only cost around 60 euros each so I think those are now on the purchase list.
