Master cylinder plug
« on: October 26, 2018, 06:17:45 PM »
I just had a master cylinder rebuilt for my Tr8 and didnt see a switch hanging out ofnthe bottom when i removed it, so im asuming it had been broken off.B  Not thinking about it after i got it back and installed i started blending the brakes and of course that didnt work out.B  Anyone know the size of that hole and the thread pitch so i can go get a plug for it?B  Ive ordered a switch but id kind of like to move the car.Jeff LyonsSent from my Sprint Phone.

As I usually see there are plenty of strong opinions but many fewer with first hand experience.Let me say I love the looks of the TR6. Back in the day when body/frame twist counted as suspension travel they were considered good handling cars. Fit one with a full cage and killer motor and they won many, many SCCA races. But those are not street cars.So let me address some of the poor electrical reputation of the TR7 & TR8. The early TR7bs had only 3 fuses in the fuse box. Have

  a problem, and sorting it is a real challenge. Later 7bs & TR8bs have double or more fuses in the box making trouble shooting easier, I think. I am not 100% sure as my 8 hasnbt given me any electrical issues. I have owned my car nearly 30 years and bought it unmolested, so I have had no trouble. The Wedges had a bmodern for the timeb electrical system. The vast majority of electrical problems I am betting is because Charles & Winston, thinking the bI can fix all 4 wires in my TR3b dive into the Wedge electrical system and are over their heads immediately, but of course that wonbt stop them.Second lets address convertible body rigidity. Have any of these critics ever driven an 80bs Camaro or Mustang convertible? I have. Due to the short wheelbase and body reinforcements of the Wedge converts I can say I have not driven nor ridden in an open topped car of similar vintage that was stiffer, it is surprisingly good.3^rd is suspension performance & ride. The ride is mode

 rn & comfortable for long distance touring. If you want performance you can stiffen it up & lower it, I have found mine, mildly modified , to be a hoot on the autocross course (if you like high speed sweepers with the steering crossed up, the tail mildy hanging out & the back tires spinning as they try to get traction. It is very chuckable, controllable and not near the bottom of the performance pile. But suspension is the carbs aftermarket Achilles heel. 13b wheels, an odd bolt pattern and small wheelwells make it impossible to get great rubber under the car at low cost, you have to spend some $$. Also the availability of bigger brakes, swaybars & other suspension goodies is limited. If you want to compete in AutoX you will have to be a DIY kind of guy with some skills, this aint a 911 or a Camaro where you can order up catalogs and have a selection of goodies from mild to wild.On the power side I have firsthand knowledge of a friend who did the following: Low restriction

  exhaust/mufflers on stock cast iron exhaust manifolds, desmogged. Fit some K&N filters in the stock airbox, set the timing to 10 deg BTDC & put different needles in the strombergs. That car went down the road at a GPS verified 131+ mph. Lets see you do that in your TR6.BB  LOLOn 10/25/2018 5:13 PM, Henri Lefebvre wrote:> The TR8 is 14 votes ahead, it is close!!!>> On Tue, Oct 23, 2018 at 10:30 PM Jack Brooks <> wrote:>>> Cool, then I just pushed it over.>>>> Jack>>>> -----Original Message----->> From: []>> On>> Behalf Of Kent Blair>> Sent: Tuesday, October 23, 2018 5:41 PM>> To:>> Cc:>> Subject: Re:  time to vote on TR8>>>> I tied it 50/50 with my wedgie vote.>>>> On Mon, Oct 22, 2018 at 11:15 AM <> wrote:>>>>> Get voting folks, as of just now, 18:13 hrs BST, the TR8 is losing the>>> vote, but not by much!>>>>>> On Sat, 20 Oct 2018, at 2

That switch is not sealed and there should be no fluid there, so if

there is fluid coming out of that hole in the bottom of the master

cylinder, there are other problems... :-(

HI Jeff,

The brake warning switch is not meant to have fluid pressure like an oil

pressure switch might. It is more like a brake light switch with a

simple plunger operating the contacts - if there is fluid pressure on

the switch, the fluid will pass right through it. If there is brake

fluid coming out of the hole that the switch mounts in, it means that

the seals on the shuttle are not sealing. The brakes should operate

quite normally with out that switch in place.

Here is a brief description of how it works:

Did the TR8bs not all have the switch with the triangular electrical plug?

Yes they did. The function was the same - just a different connector.
