How often should 5.1 brake fluid be replaced. I've had made in for just over a year now and I'm sure the brake pedal is not as firm when braking hard as used to be. Should the fluid need changing after this length of time.
I used to do it every year ... at the same time as my annual oil change, etc. (I only ever did about 5,000 miles per year, at most.)
When was your last oil and fluid change Dave?
Dan, sorry ... only just noticed this post of yours! The last fluid change (all fluids) will have been at the last service at Motormech ... as indicated in the service book. It had a service every year at the same time ... so sometime in March '10, I'd guess?
