HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Hi guys. I'm working on the brake pedal attachment to the hydroboost.

Using the TPC provided mounting plate, clevis, Ford hydroboost unit and its connecting to the late style hollow brake pedal pictured below. I test fit everything this afternoon and I'm getting binding as the pedal is depressed, seems like the clevis is angled upward too steeply. I think re-drilling the pedal slightly higher will fix this. Has anyone been down this road before with a hollow brake pedal? Any measurements on where to drill?

Thanks for any tips.

You need to drill it, and the binding is probably more because you tightened the nut on the Clovis to much where it attaches to the pedal. Ask me how I know.

OK, re-drilled the pedal slightly higher up, got a nice smooth action from the top of the travel all the way to the carpet. Re-attaching the return spring on the top of the pedal was not my favourite part of the job. What a pain. Everything is bolted up now, on to the next steps!

How do you feel about the strength of the pedal/clevis joint without the bushing like the original? I was skeptical after reading some comments here about the need for that bushing and so I picked up an early solid pedal to drill instead. That said, I have not done so yet, so I can still go either way. I seem to recall that for my setup I needed to move the hole up about 3/4 in, is that about where you ended up?

I definitely gave it some thought. Less so after having the pedal out of the car, despite being hollow it is not flimsy. I've driven vehicles with hydroboost brakes before, and they all require very little pedal effort, they feel over-boosted, so I'm not too worried that the pedal will fatigue through use.

I'd say that's about where I ended up. Basically just above the existing hole, but with enough meat between the holes to be comfortable. I held everything in place by hand and moved the pedal up and down to find smooth in and out action, then marked it and drilled on the press. I'm usually good about taking pictures but after two afternoons stuck under the pedals pictures were the last thing on my mind.

I've been working on the car again and I drilled and installed the early pedal this weekend. Only thing I'm stuck on is the pedal return spring. I might have lost it and I don't recall where it connects. I did find a spring in some misc parts bin that could be correct... Anyone have a picture or diagram of how to install? The Porsche parts diagram I've seen only shows exploded view.

You can feel where it connects to the car with your fingers, and if you are at the correct angle can actually see where it connects as well, but it's tricky and would be tough to take a picture.

This is the spring:

Super, thanks. I don't think that is the spring that I found. Current me is really cursing the old me that did such a sloppy job of documenting and tracking things several years ago... Twisted Evil
