Coupe brakes binding

Trapped pressure in the calipers. Both front brakes, or one? Could be collapsed hose internals acting as one-way valve. Could be master cylinder (or servo) restricting fluid return.

Otter Switch Fault?

The manual is not wrong - say 82C rising (on) and 78C falling (off). Any thermostat without hysteresis is useless. I guess individual switches may not be completely consistent.

Otter Switch Fault?

There will be some hysteresis, so that on and off temperatures will be different - probably about 5 deg C. Standard design requirement otherwise the switch would not know whether to be on or off.

Electric fuel pump straight 6 engine

Try a double SU pump as fitted to Astons; expensive, but does the job.

se5a stub axle

Finally got around to checking this. OS has 3/4 outer end to stub axle. NS has 5/8 ( ie the smaller diameter). No surprise given the general mismatch of components on my car.

Funny peculiar brake issue

Interesting link Joe. Did you fit this to a the smaller stub axle? It looks like a reasonable way of increasing the stiffness provided that you remember that the hub nut is to be tight, not slack. Anybody else tried this?

Funny peculiar brake issue

Master cylinder main seal not sealing as quickly as it should. Maybe poor spec rubber. Try a new seal.

What cars did you see today? (Non-Scimitar)

Rebuilt, as new, series 1 land rover on test from JLR Ryton - sounded perfect and still with protective film on exterior panels. I wonder what it will sell for?

Does the business own the freehold? Maybe lease ending? Anyone can apply for pp. Can't see the business just stopping.

Wire thickness in loom

I suggest putting a thicker wire, or double up, between alternator and battery - that will give a margin for a more powerful unit. Also a high amperage fusible link in that line is a wise precaution.

Brake Judder

You need a systematic approach - I would jack up and spin each wheel to check for wheel run-out. Then a clock gauge to check disc run-out. Then drum run-out. Then tracking.

Clutch adjustment

I doubt there is a definitive answer to the Middlebridge question. Bite nearer the floor is fine because the release bearing is further away from the release fingers (or there is slack in the cable), and consequently less/no risk of overstroking. You can play with the amount of free play, so long as...

Clutch adjustment

Simply adjust the cable to give 10mm free travel at the pedal; nothing more is needed if the linkage has the correct ratio. As the driven plate wears, the release fingers will approach the release bearing, so it will be necessary to check from time to time that free play remains. Overstroking the cl...
