So I took my 1.7 out on it's maiden voyage today and having some issues with the brakes.. They worked okay for the first 10 miles, good pressure at the pedal but didn't really slow the car down all that great. Then all of a sudden I totally lost pressure and had to pump them about 5 or 6 times to regain the pressure. Kind of scary here in the city.. So I headed home pumping the brakes a bunch before every stop. As I started pulling into the yard the pressure came back and the felt fine again. And sitting in the yard they feel okay again.. It kind of seemed like a hose burst or something but I don't see any fluid dripping on ground and the level in the master cylinder hasn't dropped any. Any idea what happened and how to fix em? The last service report which was 1,000 miles & 12 years ago said "free up calipers, replace pads, repack bearings". Also, manual says use "J1703" brake fluid, what is that? thanks!!

Thanks for the replies. Sounds like I'm gonna be checking out the whole brake system next week.. Any recommendations on what brake parts commonly need replacing? I like to have the new parts before I get into a job.. It's such a pain in the arse for me to work on anything down low on the car since I've only got a dirt/gravel yard to work in. I hope to use the car as a commuter so I want the brakes working awesome
