brake fluid vs. floor pans
Tonight I found a massive puddle of brake fluid around the pedal cluster of my '73 E (so, that is where all that fluid was going). I am going to replace the master cylinder (heavily corroded but dry). My question is, do you all think I need to pull the cluster out and do anything to the floorpan underneath to prevent rust? If so, what are your recommendations? Thanks in advance.

Far as I know, brake fluid doesn't hurt metal much. Sure eats the hell out of fiberglass & paint though!

Depending on how long you have been feeding that puddle ... you may have a little more work ahead than you planned! Some kind of treatment or conversion compound should be applied to the rusted area and that bare metal where the brake fluid removed paint. Then an epoxy such as PPG's DP40/401 Epoxy Chromate Primer should be applied.
Next, you probably should disassemble and clean the pedal cluster and replace the bushings that have swelled due to exposure to the brake fluid.

if you still have original nylon pedal bushings, they will swell up after being soaked in brake fluid and start binding the brake pedal. it might take a year, but they will swell. use metal bushings to repair.

You can use some water to help breakdown the effect's of brake fluid.

Thanks, I was afraid you would say that. Guess I know what I will be doing this weekend. I have a good start though, had to pull most of it apart just to sopp up the fluid.

Tom:
Rebuild that pedal cluster. You will be amazed at the difference with brass bushings. You might also be alarmed at the state of the bushing for the clutch cable that resides on the right end of the clutch pedal shaft, in the tunnel. Typically this bushing is on its last legs with a big chunk taken out of it. And as long as the clutch cable is unhooked, consider replacing it. Then there's the horseshoe spring (helper spring) that I am unsure if your car has... Jw EDIT: Ah, the Triumph TR6. I sold my '74 and used the money to purchase my SC (I had money left over!!). Totally redid the hardtop with new headliner, window seals, etc. Also redid the IRS, rebuilt the Strombergs and the interior as well. Fun car to drive; loved to rev it up and unload the clutch as the car lurched to one side with all the pent-up torsion in the body-on-frame slackness. And those Michelin redlines: ever ride a tire so harsh? Great car. Right there with my old '69 three-wiper MGB. [This message has been edited by Jdub (edited 10-24-2001).] |

Yes, the TR is fun but needs a little sorting out. It is a "shared custody" car between my father and me. Great cosmetic condition but I think it has had some quick mechanical fixes along the way that when they are done right it will be a great car.
