Answer 1

Hi, my name is\*\*\*\*\* to justanswer. Lets see if we cant get you rolling again. I am reviewing your case and will be with you shortly. Thank you. **\*\*. During this conversation you will be given an automated offer for a phone call from justanswer, not me. You may accept or decline that offer. I don’t personally offer this service so if you take this another tech may call. Thank you\*\*** This would be the proper procedure: 1. Right Rear 2. Left Front 3. Left Rear 4. Right Front Effectively you are doing an X-pattern, starting with the wheel furthest from the Master Cylinder.

Answer 2

Make sure your lines are not kinked anywhere as well. Also check your flexible rubber hoses at the calipers and make sure none are twisted. Make sure the calipers are not mounted up side down as well. All bleeders should be pointing up. It is always best to start with the wheel farthest away from the master cylinder.

Answer 3

There may be an automated bleed procedure required to remove trapped air from the ABS control module. This is usually done with a SAAB specific scan tool. Was the ABS light on before you started your brake repairs? One trick you can try is bleeding it with the engine running. Sometimes the extra pressure will push out trapped air.

Answer 4

Did you replace the master cylinder as well, or just the booster?

Answer 5

Have you tried driving the car after performing repairs? Sometimes the wheel speed sensors need to read wheel speed in order to reset? It does not need to be a long drive. Usually over 15mph will do the trick.

Answer 6

Have you checked for the ABS code?

Answer 7

Were any of the calipers replaced?

Answer 8

One thing that can happen as well is the inside section of the rubber hoses can break down and block the flow of brake fluid to the caliper causing two issues: Not allowing full hydraulic pressure to reach the piston, and not allowing the piston to fully release causing brake drag.

Answer 9

You are very welcome. Best of luck with your project, and happy New Year.
