Gus and the Bewitched Brakes A heat treatment teaches Mr. Pennypincher Sergeant Jerry Corcoran sat on his motorcycle parked just off the hilly main highway from the north where it crosses what we townspeople call "the outer road." He had just about decided it was time to go to a call box up the hill and make his afternoon report to the state police barracks. An old-model sedan flashed by at a brisk clip, sped through the intersection, and rolled on down the hill. Jerry wheeled out after it. When he caught up with it at the bottom of the hill, he pushed the siren button, motioned to the driver to pull over, and then did a double-take. The driver was old pinchpenny Silas Barnstable, our towns champion tightwad. Old Silas never so much as turned his head. He just gripped the wheel grimly and sped on. Jerry sounded his siren again. Gradually the car slowed to a stop. "In a hurry to get some place?" Jerry asked as he strolled back to the car after parking his motorcycle. Silas was practically half out of the drivers door, frantically explaining. "Honest, Officer, it wasnt my fault. My brakes failed. Tried to stop, but couldnt. Couldnt slow down til I could coast to a stop." "How come your brakes suddenly went bad?" questioned Jerry. "Had any trouble before this?" "Not before today," Silas replied. "Been up visitin folks on the Ridge. When I started the trek home, I began to notice everytime I came down one of those hills my brakes got a little soft. Finally, on this hill here I pushed the pedal smackdab down to the floor and still nothing happened." "No brakes, eh," Jerry remarked as he motioned to Barnstable to move over and then slid in behind the wheel himself. "Well soon see." The sergeant tried the brake pedal. There seemed to be plenty of cushion and resistance to the push of his foot. Then he stepped on the starter button, shifted, and pulled out onto the highway. When the car was hitting 30, he stepped on the brake. The old sedan eased to a perfect stop. "So, no brakes is it?" he mused as he turned the car around and headed back to where his motorcycle was parked. Jerry got out of the car and started to reach for the leather case where he kept his summons tags. "Dont give me a ticket, Officer," Silas bleated. "Those brakes must be bewitched. They wouldnt work for me." At this point, a third voice broke into the conversation. "Having trouble with this ornery citizen?" It was Gus Wilson, and, as Corcoran looked up, he noticed that Guss car was parked a short distance behind Silass. "Happened to be driving down the road, on my way to the lake to work on my boat. When I saw you here, I wondered if you needed any help running this renegade in," Gus added with a grin. "Mr. Wilson, youll vouch for me, wont you?" Silas pleaded. "Tell Sergeant Corcoran Im no law breaker. Never had a ticket in my life." "What seems to be the trouble, Jerry?" Gus asked when the whining Barnstable had subsided. "Well, I can hand at least three counts on this bird without even trying," Jerry replied as he began counting them off on his fingers. "Exceeding the speed limit, disregarding a caution signal, and failing to stop when ordered." "But it wasnt my fault, Mr. Wilson," broke in Barnstable. "My brakes went bad, and I couldnt even slow down, much less stop." "His brakes are as good as anyones," Jerry countered, as he started to write out the ticket. "Gave me the same cock-and-bull story, but I tried his brakes and they worked all right for me." Then, turning to Silas, he said, "Let me see your license, Mr. Barnstable." "But it was my brakes," Silas repeated as he dug into his battered wallet. "Maybe you are being a little hard on Silas, Jerry," Gus put in. "Could be that there is something wrong with his brakes. After all, a mans innocent until proven guilty." For some reason or other, there was something about the old skinflint that had always softened Gus. For a moment, Jerry just looked at Silas. Then, tucking his pencil into the top of his black boot, he said, "Okay, you dont deserve it, but Ill tell you what Ill do. Ill let Gus check your brakes back at his garage. If he cant find anything wrong with them, I finish writing out this ticket. If he does fond something wrong with them, youre going to pay him to fix them and Ill tear up the ticket. But therell be ho haggling over Guss price, mind you." "Humph, its a hold-up," Silas grunted. "Blackmail. Downright collusion and coercion, thats what it is. Ill . . ." He stopped short when he saw the troopers hand reach for his pencil. Then he added, "Ill do it." It was quite a procession that pulled up to the Model Garage a few minutes later. Sergeant Corcoran led the way, then came old Barnstable driving Guss car, and bring up the rear was Gus in Barnstables sedan. Jerry and Barnstable parked outside, while Gus drove Barnstables old car into the repair shop. Stan Hicks looked up from a valve job he was working on just in time to see Jerry Corcoran and Barnstable come in through the open door. "Dont tell me the old money-grubbers in trouble with the law, I hope," he said to Jerry in half a whisper. As Gus pulled his gray coveralls on over his street clothes, he asked Silas to outline his troubles. When Silas had finished, Gus asked, "Have you had your brakes checked lately? From what you say, it sounds like you may either be low on brake fluid or your brake system has a little air in it and needs bleeding." "Well, youre wrong there," Barnstable grinned cockily. "Just had em checked not four days ago down in the city. The man put in fluid too. And he didnt soak me, either," he added, waggling his finger at Gus. Ignoring Barnstable, Gus set about making a thorough step-by-step check of the brake cylinder and a check of the brake-fluid level, and ended, the car on the grease rack, by inspecting the hydraulic lines and bleeding the system at each wheel. When he finally emerged from under the raised car he was shaking his head. "Thats odd," he thought as he wiped his hands on a scrap of waste. "Plenty of fluid, no visible leaks, and no evidence of air in the lines. Yet, Silas claims his brakes went bad, and, I must admit, they did get kind of soft on the drive over here." Things werent looking too good for Barnstable as Gus finally spoke: "Its just a hunch, but theres one more test Id like to try." With that he disappeared into the garage office. When he came back, he was carrying the old reliable reflecting electric heater that Joe often used during the winter to help keep the office warm. Gathering up a long extension cord from his repair bench as he passed, Gus then rigged the heater on top of a short ladder that he placed under the raised chassis of the car. When he plugged in the extension cord, a warm red glow bathed the underside of the car. Gus had an attentive, though puzzled, audience. Jerry sat watching from a perch on one corner of the workshop bench. Silas Barnstable, standing to one side, looked for all the world like a bantam rooster as he stretched his neck and cocked his head to peer up under his car. Stan just stood there, fiddling with a thickness gauge. He was used to Guss one-man shows. "What in blazes are you doin that for?" piped Barnstable, breaking the silence. "Nothin can be froze up this time of the year." "Nope, nothin froze up," agreed Gus. "But unless I miss my guess, the heat from that heater is going to help us find whats back of your on-again, off-again brakes. I got a hunch that its been heat, and your blamed penny-pinching, that got you in trouble." Gus let the underside of the car bake for a few more minutes. Then he removed the heater and ladder and told Stan to lower the rack. As the car touched the floor, he turned to Jerry. "Now, try those brakes." Jerry followed instructions. His foot went almost to the floorboards when he pushed the pedal. As though he hadnt believed what he saw and felt, he tried the brake pedal several times more. "Well, Ill be . . ." he said as he pulled his tall frame out of the car. "How can that be?" Gus pointed an accusing thumb at old Silas. "Unfortunately, Barnstable here hasnt learned that you seldom get more than you pay for. Sure, he got a bargain from those sharpies down in the citysome cheap low-grade brake fluid. But theres no great harm done. Well flush it out and fill her up again with some good fluid." "Now you look here, Gus Wilson," exploded Barnstable. "If you think youre going to hoodwink me by selling me some fancy brake juice, youre . . ." "Easy, Silas. Remember youre dealing with Mr. Corcoran hereand a ticket." As Gus talked, he picked up the Mason jar that contained the small amount of fluid that he had bled from the brakes in checking them, and poured it into a can he had carefully cleaned. He then placed the can on a small electric hot plate at the rear of his bench. It was the hot plate that he, Joe, and Stan normally used for brewing up their midmorning and midafternoon coffee. "Now watch," Gus said as he flicked the switch. In no time at all, the fluid was beginning to bubble to a boil. "Low boiling point," he explained as he turned off the hot plate. "And thats one thing any decent brake fluid shouldnt have. Theres been a lot of low-grade brake fluids on the market lately, and most of em are just out-and-out frauds. Theyre a concoction of who-knows-what liquids that seem to work all right for ordinary driving. Sure they sell for a price, but when you need your brakes most, they dont work. Thats just what you got for your bargain, Silas." Judging from the crimson flush on old Barnstables face it was quite evident that Silas, like his low-cost brake fluid, was about to reach his own low-boiling point. "Thieves, robbers," he all but howled. "Theyll pay for this." "Now, dont go blowing a gasket," Gus put in. "Just be thankful you discovered it before you had an accident that might have killed someone. Then youd have had no alibi. When Jerry or another officer got there and tested your brakes, theyd have found them okay." "But why?" Jerry asked. "Its mostly a matter of heat. It takes about 160 horsepower to stop the average car going 60 miles an hour and that develops a heap of heat in the brakes and brake fluid. When you ride those brakes a lot in hilly country, or in heavy city traffic, the hydraulic fluid gets plenty hot. With a good high-boiling-point brake fluidlike the kinds okayed by the Society of Automotive Engineersheat causes no trouble. But with a cheap fluid, made up of low-boiling liquids, it vaporizes and forms vapor pockets in the brake system. When that happens, the brakes just wont work, just as they wouldnt work when I heated up the master brake cylinder by putting that heater close to it. Instead of pushing fluid against the brake pistons to operate the shoes, your foot pedal pushes against vapor." "But how come they worked all right a few minutes later?" Jerry asked. "When the vapor cools," Gus explained, "it condenses back to a liquid and you have a normal working braking system. That is, until you start tramping on the brake pedal again and generate more heat." "Well, which is it," Jerry asked Barnstable. "A new fill of approved brake fluid, or that ticket Ive got half filled out?" "How much will that new fluid cost me?" asked Silas, his eye still peeled for a bargain. "Only a few cents more than the stuff those cut-rate gyps sold you," Gus told him. "Its a bargain. And mind you, no funny business on extras either." "That chiseler," Stan muttered after Jerry Corcoran and Silas had left. "Ill bet hes already got a bargain set up for his own funerala nice used grave in some abandoned cemetery." "Oh, dont be too hard on old Silas," Gus philosophized. "There are a lot of Silases in the world wholl settle for cheap for a bigger deal than brake fluids and tiresif the price is right. Theyve just got a mixed-up sense of values, I guess." |
