Car Forum / Antique and Collectibles / Studebaker / September 2005Q Re Brakes
I feel like I've gotten my 64 R-1 out of a long extended hibernation. It's been a whole year since I've driven it more than a few blocks. It is running fantastic - except for the brakes - they're scary! Please help me understand what is wrong with them. At speed, the brakes will slow the car pretty well, not great, but acceptable. However, if I needed to come to a complete stop, I can apply the brakes with great force but I can't get them to lock up or even stop the car very quickly. This is most noticable coming to a stop in traffic at a light. If the choke is on, it's almost impossible to keep the car from rolling. I've installed a dual master cylinder and a proportioning valve. I can tell a small difference when adjusting the pressure to the rear brakes, but almost insignificant stopping power. Brake pressure is not spongy. System has been bled (and MC was bench bled). Any ideas? Thanks for your help, Rich Richard Morris Renton, WA 1964 Avanti R-1 #5367 1990 Avanti 4-door #78 I'd be concerned that you have no braking in the front. I'd check for stuck pistons in the front calipers, check the rears while you are there. I guess it could be the booster too. I wish I could be more specific, but you should check everything anyway. > I feel like I've gotten my 64 R-1 out of a long extended hibernation. > It's been a whole year since I've driven it more than a few blocks.

Studebaker disc brakes are somewhat unique in that the metal backing plates of the pads will hit a stop long before the lining material is worn down to nothing. If you look at pads so worn, they appear to be acceptable if you are used to judging lining thickness on Brand X cars. The symptom is a hard pedal and progressively weaker braking. Gord Richmond Going through a hedge onto someone's lawn was my way of stopping when the brake pads still showed friction makerial, Gord Or maybe that was when resting the battery on top of the booster too many time split the tube gommet at the back of the booster. Yes, ;64 GT w/PDB Karl Sounds a lot like my R1 when the brake booster failed. Good, hard pedal but virtually no stopping power. Also, as Gord stated, take a look at the front pads. If it still has the Stude disc brakes, there should be a line cut on the side of the pad. When you reach the end of that line, it is time for new pads. >I feel like I've gotten my 64 R-1 out of a long extended hibernation. >It's been a whole year since I've driven it more than a few blocks.

Guess I'll park the car until I have time to really investigate well - power booster, front pads, etc. Would hate to have put all this time, effort and money into the car just to cause an accident. Rich I second that - the brake booster went out on my R2 and had the same symptoms. Swapped it out and everything worked. > Sounds a lot like my R1 when the brake booster failed.

The only label that fits: http://www.capitolhillblue.com/artman/publish/article_6966.shtml "The President is merely the most important among a large number of public servants. He should be supported or opposed exactly to the degree which is warranted by his good conduct or bad conduct, his efficiency or inefficiency in rendering loyal, able, and disinterested service to the Nation as a whole. Therefore it is absolutely necessary that there should be full liberty to tell the truth about his acts, and this means that it is exactly necessary to blame him when he does wrong as to praise him when he does right. Any other attitude in an American citizen is both base and servile. To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. Nothing but the truth should be spoken about him or any one else. But it is even more important to tell the truth, pleasant or unpleasant, about him than about any one else." ---Teddy Roosevelt, 1918 1953 Starlight Coupe 1954 Starlight Coupe R1/4-speed 1958 Silver Hawk 1960 Frua Italia Larks (2 - they're here!) 1962 Lark VI 1962 Lark Convertible 1963 Avanti R2 R4324 1963 Lark Cruiser (R2 3/4 clone in progress) 1963 GT Hawk 1963 Daytona Wagonaire 1964 Cruiser (Survivor) 1956 2E7 2004 Porsche Carrera 4S 2000 Ducati 748 2002 Jeep Overland http://homepage.mac.com/pdrnec/PhotoAlbum81.html |
