I see a lot of posts about Improving the MGB's Brakes, and I discovered the single best improvement to the braking performance of an MGB that I could have ever imagined, was by simply doing what should be considered a routine maintenance project to replace all of the 1974 cars old brake hoses and clutch hose. I had noticed the front hoses had a few cracks in the rubber covers near the caliper and line fittings and discovered the rear hose was original dated 1973 and in even worse shape the the 1987 dated front hoses when I was replacing the Rack Boots. And for once I bought the best product I could find, the brake and clutch hose set with PTFE Stainless steel hoses with PCV covers, the car now has the best pedal and pedal feel of any MGB I have ever driven. no more lazy slow responding braking because the brake hoses were swelling and losing pressure that needed to go to the calipers and cylinder pistons. I spent right at $100.00 on the lines and $25 on the replacement DOT 5 fluid, but the first time I hit the brakes I knew it was money that was very well spent. I have full confidence in the cars Brakes again like I did when she was new to me. So if If you really want to upgrade MGB Brakes do this first if you have not already.

Get the disk brakes back up to full action and they're not all that bad.

Sounds like you did well for the buck.

This car is now very nearly completely done. Sure to find something else, but not now.........And 12 years later, I'm starting to fix things that were new when we built the car. It's pretty well de-bugged!

More people should taker that to heart. MGB brakes are very good when well maintained. The same goes for performance. You got to start with a great short block and go from there. The best performance upgrade you can have is a good well built tight engine. Same goes for brakes. The best upgrade for the buck is a well maintained and properly functioning system. If that's not good enough well then you can move on from there.

With all due respect I would have thought what you did was obvious especially if you don't know how old the components are. No point being able to go if you can't whoa.

FWIW when I rebuilt my Mk1 the only OEM brake component reused were the caliper shells.

Don't listen to the dolts that say a properly set up stock set can lock up the brakes.

Locking up brakes are out of control brakes

Anyone should know that.....

Yes!
Obviously the old cracked rubber hoses all required replacement. I have had the car since 1988 so the deterioration of the braking performance was gradual and almost unnoticed until I discovered the cracks in the brake hoses as I was replacing some leaking steering rack boots. So the question was then do you save a little money and go with stock replacement parts? Or upgrade and improve the car at the same time with the PTFE Stainless steel hoses with PCV covers? In my case I found it is better to upgrade and it was well worth the cost.

I don't believe anyone was suggesting that locked up brakes are a good thing. The point is; if the brakes are able to lock up the tires then the brakes are not the weak link.

On the track, we had a rule: "In a spin, both feet in." You wanted to lock up all four wheels simultaneously so you would move in a straight line, and disengage the clutch so the engine wouldn't stall. Saved me a few times.

William,

It should be obvious to all that preventative maintenance is the key. Anyone can get in a car and drive it down the road. Maintaining that car is the most important part of ownership, specifically when we are talking about cars of this age...

The factory MGB braking system is sufficient for "everyday driving" and general sporty driving but does have its limitations. I enjoy driving my car hard when the opportunity arises and as such have experienced front brake fading on at least one occasion. Because of this I upgraded my front brakes to the thicker V8 discs and installed discs on the rear. I've have not felt any fade since that point in time. Is this absolutely necessary? Of course not! I made a personal choice to perform the upgrade strictly for safety precautions. I'd rather have too much brake than too little...

Just my opinion based on 40 years of ownership....

Those who confuse Burro and Burrow don't know their @ss from a hole in the ground...
