Guest Posted July 3, 2000 Share Posted July 3, 2000 I need to get this straight: which exactly is the accumulator, and which is the "sphere"? Is it the ball as big as a small fist sitting next to the brake fluid reservoir? Is the "sphere" and the accumulator the same thing? Or is the sphere inside the accumulator?

Guest rong Posted July 3, 2000 Share Posted July 3, 2000 Nick.....The accumulator is the sphere. It contains a bladder that is pressurized on one side to help the power boost. If you loose that pressure (cracked bladder), the brakes DON'T work! I have recently changed it out. The only thing to remember is to de-pressurize your system before removing the sphere. It is simply screwed into the housing below it. All I did was carefully remove the existing unit and replace it with a new one ($149). My brakes returned to normal operation and the ABS works perfectly! Good Luck. Link to comment Share on other sites More sharing options...

Guest rong Posted July 18, 2000 Share Posted July 18, 2000 grouchy..etc.......I can't tell from the description, but it could very possible be the accumulator. Let me know your exact symptoms and I will try to evaluate. The Teves system is 'different'. There is a recall effort ongoing with NTSA and GM. You can catch up on that effort on this site.
