Automatic 2008 Rav4 Knocking noise when braking

I have an automatic 2008 Rav4. Lately when I brake I hear a knocking sound. At first we thought it. Was the brake pads but having those checked I was told it wasn't. Another guy thought it might be the gearbox oil and filter needed changing but I don't have a problem whatsoever with the gears or driving it. It's perfect other the this knocking sound once I hit the brakes. Any idea what this could be? Thanks.

    Thanks for your reply. I also thought it odd that a gear box oil change would solve a knocking noise in the brakes. Going this morning to another garage with this info. Thanks.

The noise will be in the brake disc rotors and could be the inside face cracked . Have a brake specialist shop do the check as the knocking noise under brakes will have nothing to do with a transmission.

How to prevent the transmission from damage
(The filter usually is screen type and can be cleaned when remove bottom cover. but this is not to be done at regular maintenance inspection.)
- Regularly check your parking space for leaks. Doesn't matter, is it the engine oil leak, power steering fluid or transmission fluid; if you discover any, get it fixed before it caused something serious.
- Once in a while check the transmission fluid level and condition. Not all cars however have the automatic transmission dipstick, in some cars, for example, in late Volkswagen models, the transmission fluid can only be checked by the dealer. Consult with your owner's manual for details. If the transmission fluid level is too low, there is a leak somewhere that needs to be fixed.
- Change the fluid as often as it said in your owner's manual or when it becomes too dark (rather brown than red) or dirty.
Also, keep in mind that an automatic transmission can not be drained completely - there is always some transmission fluid left inside the transmission (the torque converter, in the valve body, etc.) which means you only can change about %60 of the fluid at once. This is one more reason to change it more often.

- Use only the same type of the transmission fluid as specified in the owner's manual or on the dipstick. Some vehicles (e.g Dodge Caravan) are very sensitive to fluid type
- Never shift to the Reverse or Parking until the car comes to a complete stop.
- Never shift from the Parking mode when engine rpm is higher than normal idle.
- Always hold a brakes down when shifting from Parking.
- The automatic transmission can be damaged if towing with the drive wheels on the road. Always use a dolly or place powered wheels on the towing platform (if the vehicle is front wheel drive - tow it from the front leaving rear wheels on the road.

The key sentence is "KNOCKING OCCURS WHEN BRAKING AT ANY SPEED." With out being able to test drive the car I would have to say from experience it is the ROTOR. The rotor had a bump or a high spot on it. The rotor suppose to worn evenly but for some reason you did not.
The solution is you have to take the rotor out and have it machine flat.
Some time it can be machine and sometime it has to be replace.
You have to replace both rotors at the same time not one.
This is because both has to have equal size.
I do hope this help you.

SOURCE: Front driver side suspension knock over bumps

See if you can bounce car and replicate the noise. If you can, you should be able to find it, and put your hand on it. Stabilizer bushing are a place to look, both at the lower a arm and on the frame. If you narrow it down to the strut, it will need to be replaced. The front trans mount also goes bad, try putting it in drive with your foot on the brake and give it some gas and see if the engine moves an excessive amount.

Sounds like your transmission. It could be your u joints in your drive shaft. However, if its coming from the front , it is probably your transmission going bad. Check your front end out also.

94 accord banging/knocking noise when turning left

elf fi: I have a sneaky suspicion that you may have a bolt on a caliper missing. I might suggest that you jack the car up on the side in question and pull the wheel to look at the brakes. You don't have to be a tech to know if a part os missing, it should be obvious. The caliper is affixed to the car by two large bolts which go in from the back side. So you would have to look on the inside for the attaching bolts. There are two smaller bolts which attach the caliper to caliper mounting bracket, so make sure you look at both.
I have a method I had come up with when I was teaching collision repairs. I call it "SESAME STREETING". "what ever is on the left, should be on the right. Don't forget to make comparisons between opposite sides. Usually one should mirror the other. Most vehicle are symmetrical. Anyway, I would definitely be looking for a loose or missing fastener. Good luck.
