boosters for 1750 s2 coupe
« on: July 19, 2020, 06:06:28 PM »
Hey guys./
  I want to buy a new booster, is there  someone in  Australia sells the units or rebuilds???
  Price appears the same both ways, or has someone got any to sell rebuilt.

    Strange thing that notified me to problem is driving along and went to apply brakes --   pedal actually rose up!!!,  as in very stiff with hardly any travel.
   It then went down to normal pressure   and braked as normal.   On the drive  did the same thing again 2-3 times...   strange

    Situation is  leaking slightly fluid into one of the boosters.
    could this cause above to happen?

    Cheers

I found a brake place in the U.k that sold the kits for the boosters, was about 180$ Per booster, delivered to Aus. I pulled the boosters down and they were a pretty simple to put together. I found a good write up online on the process, but its fairly straightforward. Worth spending the money on having the cylinder resleeved if it is pitted. If you want a really nice job you can get the parts plated also and it will be factory finish again.
For what it is worth, I have the lockheed type Which was simple to seperate.

Another place locally that can do it all for you in power brakes SA. They have the prices to rebuild on their website. Classic Alfa online also has new units I believe and still manage to get parts to my door in Melb quicker than anyone locally.

Thankyou,  if you can send me the link that would be great ( the rebuild kit in England).
   Have one more to replace ...   
   I looked at the Classic Alfa ones but..
 In the end purchased one from Maranello Pur-sang Motors in Brunswick. They only sell rebuilt boosters and have them on the shelf on an exchange basis.

Paul Hunt at powerbrakes is the U.K place I ordered parts from. I emailed him through website. He seemed very familiar with our boosters. Still waiting on my parts to arrive, but I think lock down has held them up.  Goodluck.
