I know this is a very subjective statement and I have no way of quantifying the braking but I have been driving my car for 20 years and am sure that it just isn't stopping the way it used to.<br><br>Here is some background information:<br><br>1. I just, as in last week, replaced the brake hoses front and rear with a set of braided stainless hoses obtained from Old Phartz. I used him as opposed to Moss or other suppliers because I have BT7 front discs and stock 100 rears which take a different rear hose than the 6-cylinder cars, and he was willing to "Mix and Match" the later front hoses and original rear hose, whereas Moss only wanted to sell me two kits. It took a bit longer to obtain them than originally promised but what came in was great--actually about 3/4" more in length which made installation a bit easier.<br><br>2. I also just--last week--rebuilt the master cylinder and installed new rear wheel cylinders, and in the process flushed the hydraulic system entirely and refilled with Wilwood 570 high-temp Dot 4 fluid. The system is positively bled and the pedal is nice and hard and where it should be with just a bit of free movement.<br><br>3. The front pads and rear shoes have been replaced within the last twelve months and probably have less than 3K miles on them. Nevertheless the rotors seem to have a "glazed" appearance and the rear shoes have definitely been exposed to some slight leakage of diff oil, though not enough to saturate them.<br>Shoes and drums were cleaned following cylinder replacement.<br><br>4. I have a restrictor valve on the line to the rear brakes which, when turned down all the way, reduces fluid flow to approximately 60% of wide open. I have the valve turned all the way to reduced-flow in order to maximize fluid delivery/pressure to the front brakes as they do most of the work. There is a definite falling off in brake performance as the valve is opened.<br><br>5. The rear brakes are properly adjusted and the parking brake is functional when engaged.<br><br>6. I can, with extreme pedal pressure, lock the front brakes with little or no side-to-side pulling.<br><br>7. Tires are Michelin XAS with plenty of tread and 30 psi all around.<br><br>I just lost my lease to a warehouse space I have been renting and must clear out in a few weeks, so for that and other reasons I am not able to undertake any big project such as putting in a servo or replacing the front rotors with some racing stuff or rear brakes with discs, etc. However I am able to put on new front pads and rear shoes, and perhaps have the front rotors turned if need be. So I guess what I am looking for is some recommendations on what materials I might use to give good braking with reasonable pedal effort. I do my racing on a track in my other cars and am <b><i>not </i></b>looking to equip the Healey with rock hard pads/shoes. I merely want to improve the car's braking so I do not have to stand on the pedal to get the car to stop.<br><br><br>Best--Michael Oritt<br>1954 BN1 LeMans</blockquote></div></div></div></div></div>_______________________________________________<br>Support Team.Net <a href="http://www.team.net/donate.html" target="_blank">http://www.team.net/donate.html</a><br>Suggested annual donation $12.75<br><br>Archive: <a href="http://www.team.net/pipermail/healeys " target="_blank">http://www.team.net/pipermail/healeys </a><a href="http://autox.team.net/archive" target="_blank">http://autox.team.net/archive</a><br><br><a ymailto="mailto:Healeys@autox.team.net" href="mailto:Healeys@autox.team.net">Healeys@autox.team.net</a><br><a href="http://autox.team.net/mailman/listinfo/healeys" target="_blank">http://autox.team.net/mailman/listinfo/healeys</a><br><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/rrengineer.mike@att.net" target="_blank">http://autox.team.net/mailman/options/healeys/rrengineer.mike@att.net</a><br><br></div>
