Brakes on a 1275

Hi folks
At last I have the time to get my Morris back on the road. I pulled it last year as the brakes were behaving strangely, pulling either to the left or right -whichever way took their fancy! Not good!
I have decided to replace the master cylinder also, as that gradually allows the pedal to drop under pressure.

My question is this: On a higher powered car, is it really necessary to have enhanced brakes? Mine has a servo of unknown vintage which looks somewhat scruffy. My inclination is to strip it out and reinstate the original set up. I know that properly set up brakes, if maintained well are perfectly OK on a standard 1098. Even with a larger engine, I wouldn't be wanting to travel at higher than legal speeds (my boy-racing days are long since gone - and far too many speed cameras in Lancs!)
Also, would people advise keeping the remote brake fluid reservoir which seems to feed into the rear of the master cylinder via a tough flexible pipe. I personally have no problem with checking under the carpet regularly!
Finally, what is the general consensus on pattern brake cylinders? A well known supplier has a "do all your brakes kit" which looks tempting.

Cheers,
Dom.

Whatever you do, don't go for pattern cylinders! I've had a rear one fail on me, and its never fun, even if there were no consequences. If your happy with checking under the carpet then its fine :) They are commonly used when fitting discs due to the extra fluid that can be used as the pads wear, but apparently not essential. I too would be tempted to remove the servo if going for a standard set up, as its not necessary, and other than having to press less hard.. Discs is a personal choice I suppose. I have them on a standard 1098, as I much prefer the stopping power and imho are necessary for driving in modern traffic, but many will disagree. I guess if you are standard width wheels or not will probably effect your decision too?

As you suspect - the standard 8" front drums (but not the early 7" ones!!) will be perfectly satisfactory with any sane driving. They should be able to lock the wheels - which is all discs can do anyway..... And they really don't fade unless horribly abused. I would not renew the master cylinder at this stage. I would remove the servo (which may be the reason for sinking pedal) and yes - I would also remove the remote reservoir. Servo is sold as an 'upgrade' for the brakes - it is NOT - it simply reduces the pedal pressure slightly - but unless you have leg problems - the pressure (on well maintained brakes) is not exactly excessive in the first place. These cars were sold for 'little old ladies' and 'district nurses' to drive !

Thanks Roy,
I'll try as you suggest this week and see how it goes. I must say I'd rather leave the M/c where it is if possible!
