96 993 with 45K miles has shown a soft brake pedal. Pedal goes soft when applied down half way then is firm. Upon lifting off pedal and reapplying brake pedal is firm!

Is this an indication of brakes need to be bled OR flushed and brake fluid replaced?

No warning light for low brake pressure.

I have owned the car since 21K miles w/o any service on the brakes.

TIA

Bleed the brakes and you should be back in business!

 

On a side note, you should think about bleeding your brakes every 2 years AT LEAST, regardless of mileage. More like once a year, if you drive your car hard.

It's cheap insurance and easy to do. If you were closer, I'd even show you how to do it!

Thanks Oleg & Jeff...You confirmed my thoughts. Being a techie engineering type I will pursue the DIY @ P Car . com and brush up on the bleeding brake procedure...or take it to my wrench for a fresh fluid install..

Thanks

Have a great day! <img src="graemlins/wave.gif" border="0" alt="[byebye]" />

 

If bleeding doesn't help, flush the whole system. That's what I did after bleeding didn't help. Actually the cost of flushing the system is relatively cheap (my mechanic charged $70)so it's probably better to just flush it.

 

Same problem - after being told I needed a new ABS pump and controller (long story, would have been B$g B$cks!), flushing the brake fluid did the trick. Initially though, it still felt just a bit squishy and the diagnostics at the dealer indicated that there was still a problem with a front sensor. After a few days it firmed up and feels perfect now. I bet it would now pass the diagnostic.

Invest $45 in a Motive pressure bleeder, and buy a can of ATE super blue brake fluid. The only difference between bleeding your brakes and flushing them is how long you keep the bleed nipples open; at 45k miles, you ought to flush the brake fluid while you're bleeding them.

The blue brake fluid will make it easy to tell when you've pushed out all the old fluid.
