I can buy the Wabco shuttle valves for $80.00 but no seals included just the bolts. I think the falcon kit is a little expensive and its not even the brand name. For valves and seals on Falcon its $140.00 shipped. Like I said I am going to buy a Wabco replacement on the valves for $80.00 and if forced to buy the seals from falcon for $49.00 shipped. Anyone know of another place I can get the seals at? I think that $39.00 plus $10.00 for shipping is a rip off for 2 pieces of rubber.

I dont know how much shipping will be on it...call AB on Mon and ask them if they offer the seals too and you can save on shipping.

 

Spike wouldn't the Wabco shuttle valves be better than the Falconworks valves?

 

The seals in our 2003 Discovery were found to be leaking when we opted to have the seals replaced with Falcon seals as a preventive maintenance
(we did not replace the SVS as it tested as good).

Never had the Amigos until the ABS was opened up to have the seals replaced.

We bought the ABS Amigo to chase down the problem as the three Amigos were intermittent. The fault we found was the SVS electrical supervision (thinking back, I wished I just replaced the SVS when the seals were being replaced).

The ABS Amigo is a great product if your code reader does not have ABS diagnostics.

I did not see any others offering the seals. As for the SVS switch, we opted for the Land Rover repair kit with SVS and the Solenoid that I found one on ebay. If I was pulling the ABS apart for the SVS, I was going to do the repair right once and for all. I have no desire to be working on the ABS in zero degree weather.

Wont the new shuttle valves have the seals already on them?

 

The shuttle valve switch (SVS) does NOT come with seals. Falcon Works appears to be the only supplier of seals for Shuttle Valves (see the stickies for replacement). The SVS becomes soaked in brake fluid when the seals fail thus causing the SVS to fail.

I would recommend doing both the SVS and the Shuttle Valve seals.

I am learning as I go along if you ignore any signs of a problem you will very soon have a cascading of events. This appears to indicative of Rovers.

The bleeding will require you to trigger the ABS pump via a code scanner such as the Hawkeye or another method covered in other postings.

We did not have the Hawkeye at the time so our method was to find a gravel road and brake hard enough to cause the ABS to actuate.

The seals/o-rings are what fail in the first place, most of the time, and without replacing them at the same time, the shuttle valve will fail again.
Buy the Falcon works kit, do the full repair and the ground repair and be done with it, Period.
Also, make sure to do a full 2 quart DOT 4 brake flush to get rid of your old burned/acidic brake flush that eats up seals.

 

I bought my shuttle valve kit through a supplier we used at my previous job. It came in a Wabco box. The seals actually go on the plungers/pistons in the modulator which contact the switches. I thought I had linked to a AULRO how-to on the seals in the sticky here, when I did mine earlier this year. I simply gravity bled my brakes, then made two trips around the neighborhood in low range, 1st gear, with HDC engaged. Speed up to 10, let off the gas, and the abs engages to slow you back down. Repeat several times.

 

Morph Im paying $83 shipped for the actual Wabco valves, but will buy the seals from Falcon. I just replaced brake fluid and bled the brakes so I will take your advice and do the gravity bleed. Question all I need is to get the air out after I do the mod rebuild so cant I do it right at the ABS one line at a time? I like how you got the ABS to kick in, I will follow that.

 

You may still need to do a full bleed so have enough, 2 quarts of DOT 4 just in case.
