Re: best workshop manual

I have both the official British Leyland workshop manual and the Haynes manual. Neither is perfect. The factory manual assumes you have a garage full of special tools as it is aimed at the dealers of the day. The Haynes manual is a bit skimpy on detail, for example, "Reassembly is the reverse of dis...

Re: Spark plug socket

Remy, proper spark plug sockets are longer than standard sockets and ideally have the rubber insert so you can't crack the insulator. A 21mm is what you need. I'm fairly sure the door screws will need a number 4 Pozidrive bit. They could be very tight so be careful not to damage them. An impact driv...

Re: Brakes continually need re-bleeding / reservoir needs topping up

Well I would agree about the steering and that's why my V8 has power steering. But my 1971 roadster, which I drove to work every day for 12 years has no servo and the brakes were absolutely fine and not heavy at all. Far better than on my 1977 Dolomite which does have a servo! I'm currently rebuildi...

Re: Spark plug socket

They are standard length 14mm thread spark plugs. The correct specification is Spanner Size: 20,8 mm. Outer thread [mm]: 14,0. Thread Length [mm]: 12,7. Buy a 21mm plug socket and get one with a rubber insert to protect the ceramic insulator. 21mm plugs come in standard reach and long reach, but the...

Re: Brakes continually need re-bleeding / reservoir needs topping up

According to the official parts book and Clausager's "Original MGB", all single circuit brakes on the MGB use the same master cylinder. There was a change to the type of seals used but the bore remained the same. There is a good article on the servo on Paul Hunt's excellent site http://mgb-stuff.org...

Re: Brakes continually need re-bleeding / reservoir needs topping up

Or simply remove the servo and connect up the pipework without one. In my opinion the standard servo makes very little difference to the brakes anyway. Plus you will have a firmer pedal. After all, the first nine years of MGBs had no servo, and the brakes were identical to the ones on the servoed ca...

Re: Brakes continually need re-bleeding / reservoir needs topping up

It's not unheard of for the fluid to be collecting in the brake servo, assuming you have the remote servo mounted on the passenger side of the car. A few owners have suffered sudden alarming loss of brakes while driving when all the brake fluid has gone into the servo. It's what I would check if I w...

Re: What year is My MGB

I've had a look in Clausager's book "Original MGB" and come up with this. Certainly your car appears to be an early one. G means it is an MG H means it has an engine between 1400 and 2000 cc N means it is a two seat tourer 3 means it is a mark 1 model built between 1962 -1967. These are known as the...

Re: Bleeding the clutch

A technique I have used on several cars is to bleed it from the bottom up, the way the air naturally wants to go. I start with the system empty and connect my full Eezibleed bottle to the slave bleed nipple. Then by applying a very low pressure from the spare tyre (around 10 psi) you can watch the f...
