Is there some amazing way I can get the roll pin into the pedal clusetr? I have tried sticking it in the freezer for a few days but no joy or do I need a bigger
Cheers

Do you have a vice or a hydraulic press?
I tried (with some extra hands) putting the cluster in a vice, one site of the roll pin I put a socket and the other side a small bolt - then press it out.
Don't try to drill the thing out!
I have tapered one end of the roll pin with a grinder just enough to get it started.
Mr Shea I'm sure has a trick.
I used a vice as a makeshift press. I also warmed up the boss it goes into with a MAPP torch. Easy.

Its just a matter of getting it straight to start with...and use a punch, not a nail set...a punch the correct diameter of the pin or you peen over the end of the pin.
One end should have a slight taper...maybe both.
If not, get a grinder or hand file and taper the end a bit...just a slight camfer.

I'd like to ask why you can't replace the roll pin with a high grade metric bolt with the unthreaded shank running nearly the whole required length?

On Honda's, the shift linkage is attached at the transmission with a roll pin. It's commonly refered to as the "bitch pin" by anybody that has to deal with it.
Here is a write-up that I did showing how to do it without getting out the BFH:

It may give you some ideas.
Andys; One of the ideas behind roll pins is that they are in tight contact on the sides. This prevents any movement between the two items. If you used a bolt and the sides were not tight, you would have to tighten the nut to the point that you crush the outer piece tight against the inner piece. Of course this requires that both items have pretty much the same inside diameter. I doubt it makes any difference on a brake pedal assembly!! I'd also guess that P uses a roll pin in this location due to cost for parts and labor time being less.

Right , I 'll give this another go tomorrow. thanks for the advice.

Vise works. Press works slightly better but it's hard to position.
When I rebuild my cluster, I asked the same question. The answer was "BFH"
Worked for me.

BFH to get the roll pin in?
Check the diameter of the roll pin. Maybe they put the wrong size in your kit?? I've never had one that was that difficult to install.
Mine was horrible to install... I only got it about 90% of the way in.
I bent the handle on my vice trying to get that sucker installed. I ended up giving the whole thing to a buddy who works at a machine shop to have him press it in.
Find a machine shop and have them do it. It will be a quick and easy job for them and save you hours of frustration.
I have a special tool that fits over the end of the roll pin for the installation. I will get a picture this afternoon.
Whoever "designed " the pedal cluster is an idiot. I spent four hours trying to get the roll pin and broke the vice. Arghhhhhhhhhh

I'm going to guess again the roll pin is the wrong size. I've rebuilt at least a dozen pedal clusters and have yet to break my vise
Musta been a POS (what else) Harbor freight vise. I usually use a hammer, but occasionally a vise. never a problem. As for a bolt, you'd need a barely slip fit shaft, with a minimal head and almost no threads sticking out the other side. There has to be clearance for the shaft to rotate ......... The Cap'n
Right, I got hold of another bronze bushing set and that roll pin is just as impossible to install. In all the years of aircoolled VW's there are only two bollocks jobs. A clutch cable in a right hand drive Beetle and this bloody roll pin. This is getting silly. The part number off my bushing set is 930 423 401 90 i think...
Two things to screw up a press fit....
One, the pin is cocked.......
Two, the hole has a burr or a step in it (see thing 1 for the cause or see the burr or step caused by the punch and BFH used in removing the former pin)
I'd measure the hole with drill bits to determine the hole size ( and to clean up the step or burr imprinted in the hole...)
Then I"d measure the pin with calipers.
If there is a big difference, ya gots the wrong pin.
As per the screw, there is a reason for the pin- can you say spring steel??????
Unlike the bolt, It's harder than hell and has a little give when you slam the pedal down.....

Anybody who said wrong size pin gets a medal, looked up the number still available at Porsche ordered three and Bingo in in goes, besides now have a new vice.
Andrew, use heat. A propane or map gas torch works fine for this. You might melt the plastic bushings, but you aren't going to re-use them.
