Braking & Mounting Lowering Springs On T180

[Sinttruijen]

Just wanted te share some experience since a friend of mine also bought a T180 and dind't mount the lowering springs.

Some background info:

The T180 is equiped with a load adjusted braking system for the rear brakes. This means that when the Auris has a heavy load in the ( full trunk or many backseat drivers), the rearbrakes get more braking fluid pressure.

There is a leaver mounted in the middle of the rear suspension which meassures the hight ( read: "load") of the rear of your Auris.

Difference after mounting lowering springs:

Since you mount your lowering springs WITHOUT modifying this leaver, your braking system "thinks" your auris has a big load in the back ( lowering springs brings the back of your Auris 3 cm down) and transfers more pressure to the rear brakes.

Findings:

After driving eachother T180. Mine with lowering & my friends without, we noticed a shange in braking behavoure.

The T180 with lowering had a better response of breaking , then the without lowering springs.

The T180 without was getting heavy in stearing on the front of ther car while breaking, while the T180 with lowering springs was getting a bit "tailhappy" while breaking.

The T180 rear brakes were getting hotter with lowering springs. This means they are used more intense.

Overall, this gives in my opinion a conclusion that the rearbrakes of a standard T180 are not getting enough pressure. Therefore they stearing characteristics

while breaking are not optimal.

Conclusion:

Mount loweringsprings to improve your front- versus rear break brakes balance.

Caution:

Don't try to shorten the leaver manually, cause i have NO idea how much millimeters it has to be shortened to match the same effect gained by mounting lowering springs.

Just wanted to share my findings with you guyz & hope you guyz have some use for it

That is not right i`m afraid.

The sensor on the middle of the rear suspension has not got anything do to with the brakes, it is for adjustment of the xenon lights.

Thanks for the correction , cause the leaver was appointed after a quick inspection. mabye too quick

Cause this much difference of breaking pressure on the rear brakes between 2 T180's is too much by random change.

Then the effect of brakingpressure for the rearbrake has to be made by a different meganism then this leaver. any idea which mechanism toyota uses for this ?

thnxs,

[compressor mad]

is it all not linked through the ecu,s to the brakes actuator, the ecu takes readings from a yaw rate sensor which tells the ecu what position the car is in therefore deciding with the wheel speed sensors how much force to apply to the brakes?
