MG TD TF 1500 - Front Brakes

I know this has been covered many times before, but can't find a clear summary.

Very simply, the car pulls to the left on breaking. Checking the snails, the snail and moving piston is set up below on one side and above on the other. I know both should be either above or below, but which?

Ian. I would suggest that you have a partially seized front right wheel cylinder.
The position for the cylinders is as follows. front right brake cylinder should have the cam on the bottom. The rearmost cylinder is just the reverse.
Left wheel front cylinder shoud have the cam on the bottom . The rear cylinder has the adjuster on top. This makes the shoes leading and not trailing.

Ian,

Sandy is correct. Here is a picture of the RH side. Forward is to the right in this picture. The LH side is the same, but opposite. Note, my springs go to the widest holes, but that is the way they were when I took them apart. I've since learned that the springs go to the closer holes, with less tension, but I don't think it matters much.

warmly,

Ian,
check also your shoes. I found on my 1953 TD that the length of the brake liner was different on LH to RH. Obvious they was changed only on one side and not axle wise as it should.
Mixing the shoes eliminates the left pulling.
Good luck

Ian - Take the car on a gravel road at 10 or 15 mph and stand on the brakes, then look at the skid marks. My bet is that you will find that the right side is not braking or is braking late, the above will tell you. Once you have done that, disassemble that side and I'll bet that like Sandy suggests, you will find on of the cylinders is sticking. this is a very common problem. Cheers - Dave

Dave --- Where did you get the idea that the springs go into the holes closest to the end? I think you'll find that they go into the holes away from the end, with the greater tension. For ref. look at image M.6 in the Workshop Manual. Bud

Hi Bud!

I got it from a discussion on this board. A whole bunch of people chimed in, and essentially said that I installed mine too tight. But hey, I just looked in the manual and it appears you may be correct about page M.6... and then I read page M.12 (issue 2 (E) 8/52) and it says "the front brake wheel cylinders are interchangeable but the link pipe banjo unions must be fitted to them so the flexible hose is connected to the forward cylinder and the bleed screw to the rear cylinder." Which we know is wrong...


warmly,

Thank you all for the impeccable answers and descriptions. The cylinders on the OS front wheel was incorrectly installed.

It has taken over 2 years of ineffective tinkering to find that I hadn't a clue what was causing the drift on hard braking.

Many thanks.
