brakes

Postby beachbuddy0253 » Sat May 01, 2010 9:24 pm



i have a 1995 1500 se, the pedal for the rear brake seems as if it has a lot of travel. i put all new brakes on it this spring but it feels like i have to push it a long way down before i have good brakes, i used a vac pump on the front and rear brakes to bleed them and thought i had all the air out. i also replaced the brake fluid with synthetic. flushe about 3 resevouirs of fluid before i bled them . my 1200 i was able to reposition the pedal and had a nice high one, any ideas.

I don't know what kind of fuel did you used exactly, but you NEVER should mix DOT4 fluid with DOT5! DOT 3, 4, 5.1 fluids are glycol-based, DOT5 is silicone-based. After bleeding, you still have some old fluid in the system, so if you fill the system with DOT5, you will have a mixed fluid in the brake system. This mixture of the glycol and silicone-based fluids will damage some sealing parts and maybe the fuel lines too. Try to disassembly the whole system and clean the parts, then back to the good "old" DOT4.

I'm sure you know the 1500 have combined brake system. There's a valve in the fuel line going to the front caliper. Take a look at the valve, maybe it's gone. I have no other idea...
