MG MGB Technical - New Brakes

After all these years of fun driving, I need to replace the brakes. I would like to do the entire plumbing from the master cylinder down. I need to know what is better to replace vs. rebuild. Also any pointers to approach this job, places to get the parts etc.

Thinking about getting my parts from brittek, opinions +/-
I'm sure I'll have more questions later. Thanks all

Hi J, just doing the very same to mine. I've replaced virtually everything since the cost here is pretty minimal, and I don't want my brakes having any weak areas. MGPartsUK or the MGBHive were my suppliers, except for the hard lines which my local MG garage made up for me. The only parts I didn't replace were the 3 and 4 way unions, the rear drums and the front discs (which were new 3 years ago). Total cost about £100-150, which for peace of mind on the braking system is next to nothing. However, I guess you have a tandem circuit or brake servo - I have neither of those so it's a much simpler system to repair.

J-
Stay aeay from Chinese-made lookalike parts. You can get genuine Lockheed parts from Brit Tek at http://www.brittek.com (Brit Tek Part # ABK103).

Be sure to pull the limiting straps off of the bottom of the car, pull the rubber back, and make sure that the brake lines (pipes) are not rusty underneath the rubber. Because it only takes one pin hole in one spot to cause a system failure, make sure that you have inspected the entire system for rust. If you see any rusty, bent, or kinked brake lines (pipes) that you are concerned about, Classic Tube in New York is a fantastic source for replacing your individual or complete brake line system. They have a lot of British patterns already in stock
and provide the material in either mild steel or stainless steel with the correct flares and fittings. Plus, their brake lines (pipes) are already pre-bent on computer-controlled machines to the required lengths, angles, and orientations. I am not sure that you could buy the material, fittings, and tools for much less than what they would charge to do it for. If you have ever tried to copy some of the British line, then you know how much fun that can be. Play it safe - if you are in doubt, buy new. Classic Tube has a website at http://www.classictube.com/ .

Install a set of stainless steel-braided extruded Teflon-lined brake hoses (flexible pipes). Originally developed to handle the higher line pressures inherent in disc brake systems, these will not expand under pressure and will result in a firm brake pedal with greater “feel”, enabling you to more precisely modulate braking forces and more easily tell when the brakes are about to lock up. Due to their resistance to expansion, they also result in swifter brake system reaction time, a definite plus during hard driving on twisty roads or when forced to make a panic stop. In addition, their Teflon lining has the advantage of being impermeable to air, thus largely overcoming the problem presented by the hygroscopic properties of most brake fluids. These can also be obtained from Brit Tek.

J,


I would recommend British Sports Car Restorations. They are a Moss distributor who gives up to 16% off Moss' regualr prices. During Moss' Order Value Sale they are giving an additional 3% off orders over $200. You can see their web site at www.bscr.com.
