Hello all,
Need a bit of help for my 3.8 rebuild. Would anyone by chance happen to have a picture of the inside of the brake pedal housing showing the arrangement of the brake return spring? Or could help describe how its put back together? Someone else tool it apart and I don't have a record of what it was like assembled...
I don't know if I'm missing something obvious...
Many thanks in advance.
I-Wen

If you let me have your e mail address I'll e mail a pic. It is from a 4.2 but the principle is the same

Did this on mine last year but no pictures unfortunately. There is a either double U shaped wire spring which goes internally over the fulcrum so one side presses against the brake pedal and the other against the housing or an external coil spring. Make sure you have all the internal parts which comprise a spacing collar, special washer, large washer and self locking nut. Worth noting that the earlier cars (S1) used an external spring whilst the later ones (S2) used an internal one but that is the only difference. You can fit the S2 style spring to the earlier cars as the housing is the same.

This is the earlier one:

Oddly there are no drawings of these parts and I can find no picture of the internal spring. The part number for the internal spring is C26563.

The internal spring is the clutch pedal return which is invariably broken. Repro replacements are hopeless but you may as well fit one while you have it apart. I have a bungy strap for the clutch return now :roll:

Brake pedal David. I kept schtum because the 3.8 has a very different pedal box to my 4.2s, or the same thing on my former V12. I know the early 4.2 had a fabricated pedal box but have no idea if that uses a similar spring either, so I kept uncharacteristically schtum.

But I didn't think it was an accelerator pedal... :-)

I really need to read the posts more carefully! Sorry everybody my post regarding the accelerator spring, whilst obviously interesting, is out of place here. I will delete it later.
