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 …

Brake Pedal Clevis

Post  kevin924kevin on Tue Mar 08, 2016 7:10 pm

So question, I have my mustang hydro unit and my origanal vac booster. Removed the factory clevis and chased the tread. It is M10 x 1.25. So new hydro clevis adjustment cut hoop of and thread. So do I need to have a bushing made to account for the two different sizes. The ford clevis is to small to accommodate the factory clevis. Is this common. Also there is a consensus that the hydro has to sit at the factory angle which says here to be 12 degrees. I measured my 924 dog dish and it appears to be 7 degrees. My fire wall is 90 d to the floor as it sits. Are there different angles for our cars?

I think there is a bushing / adapter that extends the push rod if you're using this design. Post some pictures so things are more clear. Maybe the 924 is different?

Brake Pedal Clevis

Post  kevin924kevin on Thu Mar 10, 2016 5:34 pm

Thank you for the link. I will post some pics. I layed my dog bowl on a perfect level surface and measured with a protractor and my first info was confirmed mine is only 7 degrees. I measured the reset area behind the dog bowl and it is the same 7 degrees. I leveled my HB unit and the plate with it is 10 degrees. With the way the clevis on the Ford HB is installed from factory is there any leway on the angle. Or is 7 were I need to be. Also Spence supplied a link with a bunch of good drawings is the new push rod one the length require with Tha adapter for the 951 MC. If not anyone know the length etc.

The only real way to check the length of the push rod to pedal clevis is to get in there and measure. First get the unit bolted up and then adjust your push rod to meet your pedal... As I sure you know this is not going to be fun, especially if your a big guy... lol

When you get everything in place and the pedal attached to the push rod, you can then check the angle on the rod and make sure its lining up with the hydroboost unit to make sure its not going to bind. You have to make sure its going into the hydroboost nice and strait or it will tear up the seals and it will leak.

I believe the drawing for the push rod (hydroboost to master cylinder) is the one for the 944mc.

Are you using all the parts in the drawings attached? What master cylinder are you using?

is this the correct length for the HB with the adapter for the 951 MC.

So wait a minute... Are you guys saying I have to replace the pushrod that goes into my Ford HB IF I used the adapter and the 944 master? Or which pushrod are you talking about?

I am trying to figure out what lenght of push rod needed between the MC with adapter to HB unit. I dont have a rod. In this post there is a drawing spence provided for the HB units. What i want to know is this the correct lenght etc.

I would assume the push rod (HB to master) needs to be longer because of the adapter. The drawing was done by 948. This is his design...

There's obviously a drawing for the longer push rod if you looked... Its good your brakes are working fine though Laughing I didnt have to do any of this so I have no idea; Im using the ford master as is but Im using larger calipers than the porsches Very Happy

Regarding your question about the angle, i would suggest keeping it as close to the original angle as possible....not really sure how how much side loading the HB bore can withstand.

The HB to clevis adapter was made for use with a steel clevis, used on the solid brake pedals in a 944. The pushrod was made for use in-between a ford HB and 944 Turbo master cylinder.

ok i think i had a brain fart. I am going to pull the push rod out of a wrecked mustang and this should solve my issue. As Doc is using the same push rod with his adapter. I was over thinking the isssue. I hope good to go.
