Brake Servo on Series 5

[Bill & Denise Harben <harbens@JoiMail.com>]

Hi all,

After taking my series 5 for a spin last week, I noticed the brake pedal 
taking a lot more effort to slow than 6 months ago. I rebuilt the master 
cylinder (which needed it anyway) and bled everything.

It still takes what I believe is too much pressure to slow down.

Question: is there a way to test the servo to see if it is operating 
correctly?

Any other thoughts???

Thanks,
