ok... so my pedal was uber firm 3 months ago.....and just the other day i dont feel all that confident in my braking ability...i mean it stops... but the pedal is no where near as firm as it used to be....
resevoir is full.... no leaks....anywhere 6 month old SS lines..... PO's 19mm MC rebuilt M calipers and non leaking and one rebuilt rear caliper.... is my MC dying a slow and scary death? i like my pedals rock firm.... oh...btw i KNOW in the future i will be using 986 brakes..... can i use a 19mm MC with those? or will i have to buy a new one at that time (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) |

So I have a theory on brakes that progresively get worse.
THEY JUST DO THAT Since brake fluid is Hygroscopic (it absorbs water) heavy use of the brakes can make enough heat to turn the water into steam which when cools leaves air bubbles. 6 months is a long time for brake fluid. In my opinion. Hell I even bleed the Exporer brakes every 6 months. change fluid nearly every year. The 914 gets a bleed before every Autocross so thats once a month. Sometimes I get little bubbles sometimes not. But it is on the "nut & bolt check list" Stock early calipers with 17mm M/C. Seems to be better than 19mm. I like it. |
