Brakes and bushes
I finally completed some tasks that this forum had inspired me to tackle......
9000 front calipers
After some thinking time and observations on the web, I went a slightly different path in completion of the fitting. I used the small rigid brake lines from a '86 900 and mounted the support bracket in a similar positon to that of the calipers I just removed. I borrowed my brother's laser depth tool and established the thickness of the caliper metal on the 9000 caliper. (15 mm).
I drilled and tapped a thread to suit the bolt off the 900 caliper to 8mm. '93 bracket, bolt and washer, loctite.
I went to this trouble to keep the same or best pivot point on the flexible hose as was there before. Link:http://www.saabcentral.com/forums/vi...highlight=9000
Since fitting, the foot pressure required in comparison to before is definately less, however two observations in my case should be pointed out.
1. The front wheels can now be held in a locked up state if the conditions are right, damp or wet road, gravel....... looking into that one, maybe grind some of the pad material off at the edges to reduce grip so as to help the pressure release when ABS tries to act. It's that or remove the valve body and try to port the release valve!
2. I have mangaged to brake hard enough that the back wheels have lifted off the road!
I'm back in a learning phase of what to expect from the car again.
Master Cyl ABS assy
The reason I did this was the pedal was becoming inconsistant and I could feel a hint of bypass, even after bleeding 5 litres of brake fluid through in the last 12 months the fluid wouldn't stay clean and the pump time was longer than when I first bought the car. AND for only $750 the whole unit COMPLETE, better off to do it now.
Lower Front bushes.
This to hopefully cure the CRREEEAAAKK noise when traversing speed bumps or similar. So far, so good.
Keep you posted,
