Tee to replace proprtioning valve??
 

Does sombody have the part number for the Tee to replace the 914 proporting valve?? I assume it is a Porsche part. Does Pelican sell it??

Thanks,

Ken

Also available from VW...it was a squareback part...sometimes you can find them in the pick a part bone yards...

Sometimes Pelican has this part. http://www.pelicanparts.com/ultimate/smile.gif

I have to throw in my 2 Lincolns here. Don't do it! With the valve in place it will be very hard, if not imposable to lock the back tires before the front. This is a good thing. By removing the P-valve you are removing a safety feature.

If you are running stock calipers all the way around, leave the prop. valve in place. If you have upgraded the front calipers/pads substantially, then you may be able to run without the prop. valve. The purpose is to limit the rear braking power. Without a great deal better front braking, the rear brakes will lock up too easily, and hinder your ability to keep the car going the direction you want it to.
The tees are available on bugs as well as squarebacks, they are located on the drivers side of the transaxle mount, in front of the rear axle about 8".

As far as I know, all the people I have talked to that replaced the prop valve with a tee were sorry they waited so long. They experienced no early rear wheel lock up or other strange braking behavior. They did like the much more solid Pedal and easier brake bleeding. I also think those who say never to do have never tried it which is fine. What you do have to get used to is a harder/more solid pedal so a slightly different brake pedal feel is required. I have a tee on both our 914 cars and the race car has equal brakes front and rear and as far as I know all wheels lock at the same time if I goof!
Good luck.

As John knows, I'm with him. I replaced my prop valve with otherwise stock brakes. My rears don't lock and the pedal feel is not to be believed! I autocross the car and don't have any of the problems that are supposedly a consequence of having done the replacement The part cost $12.00 at a local VW shop and took about 1/2 hour to replace.

Here's a thought. If you don't mind blowing a couple of bucks and like to learn something for the investment of some time, try the swap! Of course you do have to do a very thorough system bleeding. If you don't like the results, you can always go back. I'd be willing to put some money down that you would never replace that prop valve.

Good luck!

Hey Herb did you beat me yesterday? Anyways, a handy hint if you open the brake system, remove the resevior cap and put some plastic bag over the opening with rubber bands and that will minimize the amount of brake fluid that leaks out. You'll still have to bleed ( the pump and vent will do okay or use speed bleeders) but there will be less air to remove. Good luck.

Thanks for your comments & E-Mails. I got a Tee from Perry @ "914 Network".
FYI - the Tee is going on my 914-6/3.4L race car. SC front end with Pagid Orange pads and M calipers in rear. I do not think the Front to Rear bias will be a problem.
