I have converted my 1929 rod braked car to 1930 cable brakes. What I would like is a suitable brake pedal. I have a pedal for the 1929 rod brakes if anyone would like to swap or buy.

I'm still looking for the brake pedal would a Minor one be the same?
I also need the plate that holds the gear lever in place at the top of the gear box. Round and I assume domed with a large hole to take the gear lever and four small holes to take screw to the top of the gear box. I've hunted through all the bits and pieces I have and it is not there, so can anyone help me PLEASE.

Hi John I think the pedal that you have is a Morris minor because the pedal end is oval M Type are rectangular. I don't think there is a difference between cable and Rod activation thru through pedal
Cheers pat

Thanks Tom
Pat - It could well be a Morris one. The difference is where the pedal pivot is, in the early cars it is on the end of the clutch activating rod and the pedal is to the right of the accelerator. like the one in picture, whereas on the cable braked cars it is anchored on the chassis and the pedal is in the middle, thus the bend is the other way round. At least that is what seems to be the case on all the cars I have looked at. I haven't noticed the shape of the pedals, certainly my clutch pedal that came with the car is oval and I no reason to believe that it is not original.

When the M Type was introduced, MG were under pressure to get it to the 1928 London Motor Show, so quite a lot of Morris mechanical features were carried over into the new MG because they didn't have time to do otherwise. Once the MG engineers had a chance to design desirable modifications, they launched the 1930 spec with cable brakes, new dash, brake pedal bracket etc.

Am I right about the pedal positions?

The shape of the pedal rectangular looks OK but it looks more like a clutch pedal as there is no lug for the connection to the brake shaft. So I don't think it is. It also has a way to hold the pedal to the shaft so when it is depressed the shaft rotates with it. Whereas the one I need rotates on a fixed shaft. Hope that all makes sense as the early cars the shaft rotated on the end of the clutch shaft. See my first picture and the one below.

Just to add to the fun here's a photo ( the one on right ) of a spare brake pedal I have, which I think is M type - oval pedal, canted to the left - see 2nd photo -seems right for chassis mounting. shaft dia meter .75". Happy to sell if useful to someone.
Anyone know what the other one is ? It is straight, shaft dia 0.63"

John,
Sorry about the typo, now corrected.
You are right. There should be a drilled lug just above the pivot hole, otherwise you have nothing to connect the pedal to the cross-shaft lug. I have tried unsuccessfully to find a picture but I can confirm that there is no crank in the pedal shaft: it rises straight up but has the elbow shape to present the face of the pedal to the foot. The chassis-mounted bracket provides enough displacement to the left to get it correctly aligned in the footwell, just inside the bodywork. So Tom's top picture, with the elongated rectangular top looks right apart from the absent connecting lug. ja.mcnab's lower picture would probably work but I wouldn't fancy doing an emergency stop with a pedal shaft that has that big hole in it!

There is no " big hole" in the pedal - there is a round chalk mark on the smaller on - but it has provision for a cotter pin, so id not M type.May be a clutch pedal.
The one with the chain on it is marked " Morris ".
What is the diameter of the shaft on the chassis bracket on an M type ? 0.75" or 0.61" |

Sorry Allan I too thought there was a hole in the pedal. Below is a picture of my clutch shaft which where the pedals should go it is 3/4" (0.75 in) but you can just see that the shorter end has been machined down to approx 0.621in this end is just the bearing on the opposite side of the clutch, i.e. the nearside. My shaft has been cut down at sometime so only the clutch pedal was on it. I think my car may have had an alternative braking system as the original hand brake had been disconnected, the hand brake was connected to the brake shaft and only two other brackets at either end remain, which rather indicates that it may have been fitted with hydraulic brakes.
I would think that all brake pedals have a lug on them whereas clutch pedals do not, likewise I would have thought that both have a tail at the bottom to take the return spring.
I maybe wrong, as my wife tells me, I frequently am.
