Re: Booster Upgrade

Man I'm glad I saw this right after joining. I've currently got an 87 that the booster is about shot. Has a fat vacuum leak ( brakes still work though) so I think instead of replacing with factory parts, it'd be a good time to upgrade.

I've done both.

XJ, you don't have to mess with the firewall. No big deal anyway.
But, you have to move the washer reservoir. And, once the original booster comes out, the bracket inside the cab moves and makes it a bear to install the new booster.

WJ you have to bend or cut the firewall lip, but don't move the washer bottle.
As an added bonus, the mounting studs of the WJ booster are a bit smaller and it's easier to get in.
Another bonus with the WJ is that it has FLEXIBLE lines from the master cylinder that make putting things together MUCH easier.

And, WJ boosters are newer and easier to findů..
Got some questions

1... For my 1990 XJ, which year WJ booster is used for this upgrade?

2... given I have rear discs on my XJ ( Ford Explorer disc) do I keep my proportioning valve, eliminate the valve, or use a WJ valve, or...?

3... Is the WJ master used with this conversion?

thanks

Re: Booster Upgrade

99 t0 2004 WJ booster/master assembly with the flexible lines. Grab the guts of the prop valve from the donor WJ and swap them into your prop valve.

Thank you

Re: Booster Upgrade

Are you buying the parts new, or getting them from a junkyard?

Re: Booster Upgrade

No. But you may have to cut the lip on the firewall a bit.

Simple to do. I have photos but I can't post them here. Give me an email address and I'll send them to you.

As for those lines, they should be available from the dealer.

Re: Booster Upgrade

For the brake lines is it better to buy the 2 original spare parts (whose codes I cannot find in the spare parts catalog) or take the AGS pipes and fittings ?

Re: Booster Upgrade

2 original is best.
You will need a flaring tool to change the end at the proportioning valve.

Hey, I just went through this.

I used these to convert the bubble flared metric fittings on the WJ MC to standard 3/16 24 inverted.
BLA-O380
BLA-B312
BLU-3 ( two of these )

Then I made lines from the BLU-3's to the prop valve. You can purchase the two prop valve fittings on the AGS site as well.

You will need an inverted double flare tool. Do not use the rented ones as they are trash. Purchase the Napa SER 161A.

You could also purchase just the fittings and run a new lines, but since one of mine was frozen in the prop valve I had no choice.

I also added the 1/4 inch spacer in between the booster and the firewall. My pedal is 4.5 inches from the floor. It was 5 inches from the floor with the old booster. So the space is not required.

It will lock up the front tires now and feels safer so it's def worth the headache.

Hope this helps.
