Celica :: 1992 - Brake Pedal Pulsates At A Rate Directly Proportional To How Fast Car Is Going
Oct 24, 2012
1992 Celica with about 130k miles.
The brake pedal pulsates at a rate directly proportional to how fast the car is going. How violent the pulsing is depends on how hard you apply the pedal but even at less than 5mph and even when barely applying the brake you can feel it in the pedal.
I've had this before on other vehicles and the fix was swapping rotors. Rotors are cheap enough for it so I changed the front and then the rear with no real change from either swap. As part of the swap I wire brushed the face of the hubs to make sure there wasn't rust buildup on them. Replaced a wheel bearing on the passenger front as it had some play in it. Swapped tie rod ends as they had some play. Bled brakes enough to refresh the fluid.
The changes have made it drive a little better (at least I like to think they did) but the pedal is almost completely unchanged.
I think that to feel it in the pedal it has to be an irregularity in the rotor or something else causing the piston in the caliper to move.

92 Celica at speeds of 35 or less brakes feel fine. At higher speeds the pedal sorta chatters with light pressure. If I press harder the pedal is smooth. Is this warped rotors or possibly something loose in the assembly? The car does not pull to either side the brake pedal just vibrates under light pressure at higher stopping speeds.
If it is a warped rotor will I be able to check for it with a mic or caliper? I do not have a dial indicator to check run in or run out. I do use a good machine shop with an machinist that I trust, but I would rather not pull rotors unless I have to.
Now I know this is not just tired mechanic syndrome and is a real problem with the car.

I have a 1999 Subaru Legacy 2.5 GT and I get a whining noise that is directly proportional to road speed when I drive. The noise is ONLY heard when the car is moving and your foot is on the gas. The second you lift your foot to coast the whining stops. If you are stopped, no whine. If you change gears, the frequency of the whine doesn't change. Turning the wheel left/right doesn't change anything. If it sounds like anything I've heard, it sounds like a dry differential. I've checked the front diff fluid level (the whine comes from the front) and the fluid level is full.

I have an issue that i have been trying to resolve. When i depress the brake lightly to a stop, the pedal pulsates. But if I depress a little harder it pulsates initially midway down and then it stops as i press harder to brake. (I hope this is easy to understand). so... press lightly, pulsates until I reach a stop. press firmly, pulsates briefly, then no pulsation until i reach a stop.
I have pretty much replaced everything. Calipers, rotors, pads, lnes, fluid, hardware. lugs are torqued to 100ftlbs.
Also the caliper is not sticking the problem persists even after I replaced the calipers. I am left at a total loss here. I cant think of anything else. One thing that i noticed is, the LUGS are really hot to the touch after driving it for 15 min or so.

I have a 2010 Ford ranger sport 4x4, manual, and when backing up at a decent speed, then press the brake to slow up then depress the clutch, the brake pedal pulsates and it feels like something is grinding. It has happened in first once, but I can make it happen in reverse anytime...

So I got my 92 Celica GT 2.2 Motor Auto (unfortunately for now). Back off my wife's uncle and it wont crank or anything. I also noticed that now when you push the brake, it still wont let u shift it out of park. If you try to start the car it does nothing, however the brake light on the dash shows up. I am thinking it may be the starter as all the relays and fuses look ok. I am thinking it could be the ignition switch as it wont let me shift out of park without using the release button, but am not sure where I should start.

When I release the brake pedal too fast, the brake pedal bounces back with sound which is a little bit loud to me. I feel the sound is from the spring if there's one. It's annoying so I have to remove my foot from the brake very slowly. Is it normal?

My Dads 92 Volvo's engine is making a knocking noise and I'm wondering what the possible causes are. He doesn't take that great care of it but it didn't over heat or anything. It sounds like it is making a loud knocking or clicking noise directly from the engine when you accelerate. It still runs but definitely has a lack of power.

This happens to me again on a very hot day. The symptom is: all of sudden, the brake pedal becomes stiff. I mean I can only depress down the pedal just a little bit. Then when I want to accelerate, the engine works very hard and speed picks up very slowly. RPM will shoot to 3000. When I remove my foot from the gas pedal, the speed drops very fast. The car slows down much sooner than usual. So my feeling is the brake is dragging the car. The dealer cannot duplicate the problem during short test drive. So what can be wrong? The brake booster was replaced a few months ago. Is it possible it provides too much boost?

My 1987 toyota celica brake pedal is going to the floor when I apply the brakes but not all the time,i checked the pads and shoes they are still good i also bled the brakes, I am thinking it is the master cylinder or maybe the master cylinder needs to be bled.

Its a 2007 f150 v6. has 55,000 miles. just got her new tires for Christmas. the truck has doing this for awhile. when you use the brakes the pedal pulsates and the truck jerks back and forth. Feels like bent rotor or something. I've been doing it about a year keeps getting worse. Last year I had the rotors turned and put new pads on got a little better. But not for long continued to get worse again. So I just bought new rotors and pads and still sucks. I thought it could be a bent rim so I just rotated the tires and still no better. Where should i go from here? calipers? something in the front end loose?

I have a 1986 Toyota Camry. I drove it for a year with no additional problems than when I bought it. I replaced the clutch when I bought it. However, It recently has had a new problem. The clutch pedal is going directly to the floor with no effort whatsoever. When this happened in the past it was simply out of clutch fluid, I was aware of the leak when I bought the car. Now it doesn't seem to be using any at all and I can only put it in gear when it is turned off.
I have replaced the clutch master cylinder myself and it didn't seem to solve the problem. I have tried to bleed the new master cylinder but no fluid is being drawn into the master cylinder from the fill cup on the top of it. I'm not even sure that this is the problem. I noticed that the place where the MC is attached to the clutch pedal is adjustable. Could this be a matter of adjusting this to drive the plunger inside the MC all the way forward? I am also having trouble understanding the whole clutch system. The MC doesn't seem to have anything to do with engaging or disengaging the clutch. The only thing it attaches to is the clutch pedal. Where does the clutch fluid go? Is there another place to fill Manual transmission fluid?

I might be getting a 78 celica gt 5-speed and with the stock 2.2 ... It doesn't really go very fast and I am trying to figure out what I want to do to this thing. so far I kinda like the idea of shoving a 350 under the hood but i kinda wanna stick with putting a toyota motor in it.

I have a 1992 celica 2.2. Its had been running fine till this summer. I go and start it up this morning and drive a mile or so turn the car off go take care of some stuff letting it sit for about and hour and a half. Start it back up then go to drive off and it dies and won't start back up. I let it sit for an hour and then it started back up and drove fine.
I have replaced the spark plugs, and the ignition coil inside the distributor and checked for codes but got none.
I starts fine on the first start of the day but after that it doesn't want to start.

My 1992 Toyota, Celica had developed a really weird idle surge. The idle surges between 500 to 750 rpm. The surge goes away with the AC on and it idles steady at 900 Rpm. It also has a slight off idle bog that may just be another symptom of the weird idle.
I did the diagnostic test today and it doesn't flash any codes. I pulled the EGR valve off and cleaned the gunk out of it and it didn't make any difference. I tried to check the timing and it idles so bad the timing bounces 7-10 degrees with the surge. When I did the jumper to check the timing it would kill the engine. The plugs and wires are new with in a couple thousand miles. It runs fine above idle and pulls to redline easily in the lower gears.
Yesterday when I was messing with it I had the car running with the air boot from the air cleaner to throttle body off. I sprayed carb cleaner into throttle body and it seems to clear up a little bit. Then it went back to surging again.
I tried to pull the TPS off yesterday and of course the bottom screw stripped out. Now I will have to pull the throttle body off to get the screw out. I wish it would throw a code so I could have it give me a clue.

I just bought this little car. It ticks at an idle and it burns 1/4 qt of oil a month. It doesn't stop ticking when I add oil so Im at a loss.. It isn't a loud tick either. It has 200,000 miles on it but it is in great condition besides this.

I have a 1992 celica GT 2.2l A/T. I was on my way home today from college and my car started to overheat right before i made it home. It was steaming a bit and the temp gauge was tacked out. when i pulled into my apartment i noticed a light brown colored liquid in my parking spot, and alot of it.
I saw this same liquid at my college campus and assumed it was a coffee someone spilled near my car, but now i know it came from my car. I haven't had a chance to check my houses yet as i just got home and my cars still really hot. I know its not power steering fluid b/c that's been empty all week b/c my reservoir leaks. Why my car is overheating and what liquid is coming from it. Oh also the liquid seems to be coming from the right front portion of the car.
