Ask The Mechanic – Sticky throttle pedals

This edition we focus on sticky throttle pedals, courtesy of club member John “Undie” Underwood and his late bay “LottyAnne”. If you have a technical way forward with your vehicle, email editor@vwt2oc.co.uk for inclusion in a future post.

Since many of you have probably had the pain before me, let me see if what I have done helps you out. At first, I thought that it was the throttle cable catching through the tinware after my last one snapped, no not this time! Next, as Phil mentioned it could be the nuts on the carb linkage catching the tinware or shroud housing? Not this either! The only place now was at the front! First, I took off the pedal cover underneath, and checked the end plate had no muck or grime, then took the cover off the link arm in the driver’s footwell and checked all here, even the spring on the back of the pedal. Pushing down on the pedal, I noticed the two side plates that connect the pedal to the link arm seemed to be rubbing.

Checking the comments from my post, Nick Gillott suggested I try Buttysbits. The resulting conflab with owner Simon came up with the only (at the moment!) possible solution, which was to replace these plates with new stainless-steel ones, and he would also throw in a newly manufactured pedal link arm end plate. If I gave him a mention in our group! The new bits arrived and without too much technical know-how, I replaced the parts in question.

As you can see, no need to undo any of the cables at the engine end, just release the cable from the end plate and attach new then attach to the link arm. Straight away I noticed that the accelerator pedal is now in a more upright position! First couple of depressions on the pedal instantly gave me a smoother response. Happy days! BUT as a note, I will say this new pedal height, apart from feeling like my old Beetle throttle pedal, gives me a more responsive acceleration, but tick over is slightly higher, thus the need to adjust the end plate stopper down to slow the tick over, again without the need to adjust the cable at the engine end. The new plate has been manufactured to a slightly different angle to the original ones, hence higher it the pedal height.

Notice the new angle of those link plates to those in the first photo. I have been running this now for over a week and, touch wood, I have had no sticky pedal or any other issues, I recommend this product for others experiencing this issue as along with other products from BUTTYSBITS.
