MG TD TF 1500 - Brake bushing replacement

My brake pedal is 'wobbly' whereas my clutch pedal is fine. I assume this means the bushings in the frame are OK, but the brake pedal bushing is worn. Someone told me that the pedal shaft could be moved outwards if the clutch pinch bolt, circlip and the nut and bracket on the inward end of the pedal shaft are removed. If this is so, I could move the shaft enough to take out the brake pedal and replace the bushing I suppose. I have only seen procedures to remove the pedal shaft which say drift towards the gear box. Is removing the nut on the end with the bracket advisable? Ron

Ron - You have mail.

My advice on the job you are considering is: if the brake pedal doesn't wobble enough to foul the clutch pedal, leave it alone! One only want's to tackle the job when some great big mean SOB has a gun to your head! I did mine when I had the body off of the frame and it was bad enough then. It is just a dirty, nasty job with all sorts of hidden pitfalls involved and you need all of the advantage you can get (like being able to see what you are doing) before attempting it. Good luck - Dave

Ron,

I think someone is mistaken., if we are talking about a LHD car. The pedal shaft has an arm welded at the gearbox end which is the actuating bellcrank for the clutch. That end of the arm HAS to pass through the removable cover on the gear box side of the pedal box to withdraw the shaft far enough to get the clutch pedal, spacer and finally the brake pedal off.

I don't know of any other way.

Here are two pictures to view:

Ron;
Dave Braun is 100 % correct. The arm Moss # 190500 (pedal shaft) is usually worn too much to just replace the bushing # 330100 Moss. The bushing is bronze and wears at a much slower rate than that of the pedal shaft.
Dave Dubois is also correct in that if the pedals don't clash leave well enough alone. To do the job at least the left floor board must be removed and the car jacked high enough to work easily underneath. a full hoist is best.Also if you do it replace the two bushings in the frame # 330358 Moss.To replace them at this time will save a lot of duplicate labor later.

Dave B...

Boy, that frame looks like new... no pitting under that new paint????

The shaft on my TF was pretty worn so I welded it up and then ground back down with new bushings and a new grease zerk. Very smooth with no play at the present. Body is still off so it wasn't all that bad. Would probably suck if I had to do it with the body in the way.

Gordon,

I was very lucky. The only pitting is a bit at the front where the bumper mounts, and on one or two of the tub mounts. The rest of the frame was really smooth once I sandblasted it.

I think my wood mostly rotted from dryness, not from moisture. So almost all the metal parts of my car are pretty nice. The parts that might have rusted were so caked with oil and grease so as to prevent any rust.

Ron,

Dave Dubois is correct (he posted while I was still thinking about my answer and decided to add the pictures) the pedal shaft work is very difficult. I've done it both with the tub and flooring in place, and on my empty chasis. Sandy alludes to replacing the bushings in the frame at the same time, and that is a good idea. I did find that the bronze bushes are very easy to damage if forced in. The best procedure is to press them in gradually using fender washers and a long bolt. I also replaced the shaft at the same time. Just removing the clutch clevis pin and rod is tough. I have found that with regard to the brake pedal and spring, you must remove the spring, and then remove the rod, clevis and pin, leaving he master cylinder in place. Finally, getting the spring clip back into position can be a challenge. I've broken them in the process, and hardware store replacements need massaging.

Good luck,

Really dig around in the archives. I think this was gone through in great detail a couple years ago. Totally the worst thing to do on a TD/TF. Don't do it unless really sloppy! George
