Question about 2006 Chevrolet Trailblazer

1 Answer

Brakes do not hold at steep angles. When I went down hill at steep angles my brakes lost grip and did not pump back up on the first or second try. By then I gained speed fast and was close to losing control down a steep canyon I stopped after steering into the bank and pumping the brakes hard, I did stop but barely.

The Brakes locked when going down a hill


the condition you have experienced is called brake fade . It occurs when there is insufficient brake pad to adsorb the heat generated buy the changing of the kinetics energy (spinning) into heat energy by the friction of the brake pads on the disc rotors.. It gets to a point where the pads and discs will not take any more heat so when that happens it does not matter how hard you push the pedal there will be no brakes. To prevent this happening again fit new brake pads and fit new disc rotors. If you are going to be doing steep hill work then get a brake pad suitable for hard work. Talk to a brake shop specialist to get the best pads for the job. Another experience that you will have is when the brakes get hot the pedal goes to the floor. This comes from bad brake fluid and happens when the brake fluid absorbs moisture from the air and the boiling point of the fluid is lowered considerably. The oil boils and the water in the oil turns to steam and you get vapour lock in the system and you will loose brakes as you are compressing steam or air.. The fix for that is to ensure that you change your brake fluid every 12 months.

Shakes when i put on the brakes


Hi there,

It is possible that one (or more) of your brake discs (or related components) are warped. This occurs when your brakes have been used for extended periods (e.g. braking for a long period down a steep hill, or harsh braking at high speed), causing overheating of the discs or components.

Have your brakes checked. If discs are warped, they can be machined back to a nice flat surface.

If brakes are ok, then the shaking may be related to the suspension.

My 2011 Sonata cruise control stops working going down steep hills. The set light goes off. I had it set at 50mph but applied brakes when it increased to 70mph. Dealership says they can find nothing...


going down steep hills will all but over ride a cruise control, since the motor is trying to keep the vehicle slowed to what your desired speed that you set , unfortunately this doesn't always work,, as your speed increases, the motor can't keep the speed reduced, when you apply the brakes, the system shuts off, cruise controls were meant to be used pretty much on long flat surfaces with Low inclines ,,

I have toyota axio g grade 2007 december car.what does it mean S & B in gear system.


The short answer:

S is for low speeds with quick pickup.
S is not economical. Thats why the eco light is off.

Use B when you're climbing down steep hills and needs to slow down without overheating the brakes.


The long answer:
  • Brake (B)A mode selectable on some Toyota models. In non-hybrid cars, this mode lets the engine do compression braking, also known as engine braking, typically when encountering a steep downhill. Instead of engaging the brakes, the engine in a non-hybrid car switches to a lower gear and slows down the spinning tires. The engine holds the car back, instead of the brakes slowing it down. For hybrid cars, this mode converts the electric motor into a generator for the battery. It is not the same as downshifting in a non-hybrid car, but it has the same effect in slowing the car without using the brakes. GM called this HR (hill retarder) and GR (grade retarder) in the 1950s.


S has 2 possibilities

  • Second (2 or S)This mode limits the transmission to the first two gear ratios, or locks the transmission in second gear on Ford, Kia, and Honda models. This can be used to drive in adverse conditions such as snow and ice, as well as climbing or going down hills in the winter time. Some vehicles will automatically shift up out of second gear in this mode if a certain RPM range is reached in order to prevent engine damage. Although traditionally considered second gear, there are other names used. Chrysler models with a three-speed automatic since the late 1980s have called this gear 3 while using the traditional names for Drive and Low.
  • S or SportThis is commonly described as 'Sport mode'. It operates in an identical manner as 'D' mode, except that the upshifts change much higher up the engine's rev range. This has the effect on maximising all the available engine output, and therefore enhances the performance of the vehicle, particularly during acceleration. This mode will also downchange much higher up the rev range compared to 'D' mode, maximising the effects of engine braking. This mode will have a detrimental effect on fuel economy. Hyundai has a Norm/Power switch next to the gearshift for this purpose on the Tiburon. GM also used S to indicate a "super" mode, being the same as the 2 position on a Chrysler, shifting between only first and second gears.


Dont use B or S for general driving as both are very low on fuel efficiency.

Is it normal to hear a sound going down hills around steep corners when you press on the brakes. I believe it is the stabilizing abs system which makes the sound. It is only heard when going down hills...


Hello and welcome to FixYa!
Yes it can be but I do suspect that you have worn out suspension bushings too. Try to check the brake pads as well for it may need replacement. But stabilizing abs and suspension must be the first to check.

Hope this helps and thank you for using FixYa! Have a good one!

I have a 1995 mercury sable its an automatic. I need to know which D should i be driving in. The frist D or the Second D.


use the first D. this is overdrive. it gives you the best fuel economy. The second D downshifts the transmission into a lower gear. this would be used when climbing a steep hill (it keeps the transmission from hunting between gears) or descending an equally steep hill as it would help slow the car without using the brakes.

Want go in reverse


two things that i would check first, make sure parking brake is off, then check trans fluid level (engine running, in park, on level ground) also do you park the vehical on level ground at night? my car acted like that the other day, my driveway is at a steep angle, parking it nose up hill, when backing out, it coasted back no problem but when i hit the gas to back up a little more, i got nothing. waited a few seconds then it grabbed. then i backed up with no problem.

95 325 is e-brake doesn't fully engage


Adjustment will usually help, but try parking with front pointing down hill next time.(back in, apply E brake .) Emergency brakes usually hold better/well when vehicle front heading down hill. If it doesn't hold with front pointing down, then rear brakes need attention.
