Brake issues

I have not been very pleased with my 2002 986S's brakes for some time. They feel a little soft. They stop fine, but the feel is not very firm. I have bled, bled, bled them and they don't ever get better.

Since it is April in Indiana there has been a lot of rain lately. I was driving in the rain and hit a slick spot, the PSM kicked in, as it should, and worked perfectly. When I applied the brakes, they were there!!! Nice and firm!!! These are the brakes a Porsche should have!!!

That led me to thinking.... last winter as I was putting some items in my front trunk I hit the break fluid reservoir and it cracked. I ordered the part and replaced it easily.

Now to my question/thought... I am thinking that maybe during the reservoir replacement process I got air into the ABS and when the PSM kicks in it pumps the ABS and stiffens it up the lines, similar to how pumping the brakes stiffen the pedal. So... If I have the ABS bled with a PST2, this should fix the problem... correct?

Any thoughts or advice would be greatly appreciated!

Sorry to be a school teacher but it's spelled "brakes" not "breaks" :D

I have a similar issue. I haven't found a cause either.

Hopefully someone will chime and help

:blush: And I read through it TWICE to check for things like that!!!!

I'll just blame it on the fact that I have my sleeping 10 month old daughter on my lap.... :oops:

I guess that shows how much I REALLY need a BREAK!!!! :D

Yes, a PST2 bleed with ABS bleed may help.

Phillip,

Did you get this problem fixed?. I have the same problem, so I want to know if the problem was fixed by activating the ABS using PST2 or dealer tool.

Thanks Abbiy:thankyou:
