MG MGA - Bore

Anyone know offhand what the bore dia of a DeLuxe brake master cylinder is?

Hi Nick

If it is an original dunlop cylinder, its 7/8". It's the same as a twin cam

If it is NOT "NEW", it is WHATEVER THE OVERHAULER "HONED IT OUT" to! (Assuming he did the job properly and didn't just "Throw in NEW SEALS!") Sorry, but I don't know what is the MAXIMUM it should be "HONED OUT" to, but if its TOO MUCH, you will have A VERY SHORT-LIVED BRAKE REPAIR JOB!

WHAT IS WITH ALL THIS SHOUTING and then speaking normally AND THEN SHOUTING AGAIN and then SOME SHOUTING followed closely BY MORE SHOUTING!!! are you having a REALLY BAD DAY!!!

Honing by itself rarely will remove enough metal to render standard seals useless. Re-boring followed by honing is another matter however.
