jeromio Posted August 11, 2001 Share Posted August 11, 2001 Okay. Finally got all the right parts. Now I have a rather dumb question. There are 2 ports, the one nearest the firewall is labelled "F" and the one towards the front of the car is labelled "R". These each feed into the brake warning light doodad. The front of the doodad has t ports which lead to the front calipers. The back (closer to the firewall) of the doodad leads to the rear brakes. Well, on my car, the front of the doodad is connected to the "R" M/C port and the rear is connected to the "F" port (which also has a larger reservoir for the larger front calipers). So, this is backwards, right? Essentially my "R" port is feeding the Front brakes. So, I am going to switch this around unless I hear differently from anyone here.....

Guest rooh Posted August 11, 2001 Share Posted August 11, 2001 According to the book, "F" is the front all the way through, and rear is "R",it's a presure valve on the fire wall that is a safty thing. If you loose presure it shuts off the side that looses the presure. Quote Link to comment Share on other sites More sharing options...
jeromio Posted August 12, 2001 Author Share Posted August 12, 2001 Well, it's not that I didn't understand the workings of the "doodad", just that I wanted confirmation that some previous owner had switched the lines on me. I actually confirmed the sitchatashun by blowing up the brake system diagram from my shop manual. It's hard to make out, but the lines are supposed to criss-cross from the master to the switch doodad. Quote Link to comment Share on other sites More sharing options...
pparaska Posted August 12, 2001 Share Posted August 12, 2001 Watch out. Somewhere in 70-73, it got switched from not being criss-crossed to being criss-crossed. Eric? (Neyerlin) You know when that happened? Quote Link to comment Share on other sites More sharing options...
jeromio Posted August 12, 2001 Author Share Posted August 12, 2001 That's a picture from the 77 manual. BUT, I traced all the lines. If they criss-cross from the M/C to the switch, then "F" goes to the front and "R" goes to the rear. So, it was done wrongly in the past by someone, and I have undone their doings....
