Master cylinder

I have a 1988 Fleetwood Southwind MH that I am rebuilding the brakes on. I need to know which reservoir of the master cylinder is used for the front brakes.
The VIN is 1GBKP37W4J3332544.
Any help will be greatly appreciated.

Thanks
  • First step is I will "dry fit" the master cylinder so that I can make the two brake lines between it and the distribution block assembly.
    Then I will bench bleed the master cylinder and connect it to the new lines.
    Then I will power bleed all the brakes starting with the passenger side rear and finishing with the driver's side front.
    I think that I will have completed the brake rebuild and will have to take it out for a road test...not too far from home however.
    Thanks to all of you for your responses.

    I have never worked on a motor home, but have on many cars, and that is how all of them worked.
  • But, you will want to bleed both front and rear brakes so that you have fresh, non-hydrated brake fluid in the whole system.
  • According to my P30 manual it appears that the rear reservoir feeds the front brakes and the front reservoir feeds the rear brakes.
  • I've got a chassis manual around here somewhere for the P-30
    Can't find it right now.
    I'm sure you couldn't put them in wrong without rebending them.
    See if you can locate Oldused bear on this site.
  • The chassis is a Chevrolet P37 (aka P30). The brake lines from the master cylinder were removed and now I am replacing the master cylinder and just need to make certain I have the lines installed correctly.
  • What chassis do you have?
    Can you open the bleeder screw & watch the reseivor level drop?
