I have 09 Lexus IS350 running about 50k mile with new brake pad, my brake feel delay on stop , or have to push hard for stop on fast drive, i was bring it to a auto shop and check the brake fluid was OK . anyone know whats happen on my vehicle ?

 

Many shops will perform free brake inspections, find a local one that does and have them test drive it.

 

One of the shop they told me the fluid pressure not enough , they ask me to change the whole brake unit ......
I saw one of the post on forums , they said maybe the wire issues , is that true ?

What pads did you have before, and what pads do you have now? It's possible that your new pads are just a lot less grabby than the old ones were.

 

I am using 04465-30450 OEM low dust now , I was use 04465-30500 high friction before .

 

There's your answer. But you can change out the whole brake unit (?) if you like!

 

No , The brake pad will not affect i need to push hard on brake pedal. its feeling delay . just like the brake caliper is not fully bite on the dish.

 

The original is same one i am using . Brake pads should not be a problem .

 

Your statement is 100% incorrect. The low dust pads certainly will affect how hard you have to push the pedal to make the car stop. That's the whole point of the high friction pads, they bite very hard with very little force on the pedal.

 

This is how my car felt before I found out the rear calipers were seized

 

Okay, i am gonna change the pad again..... what pad do you recommend ? still use OEM or after market ?

 

The Akebono ceramic pads perform like the high-friction OEMs, but have MUCH less brake dust. MANY members use them and love them...I do!

 

Can you send me a direct link with a best price to shop for it ? I have 09 IS350 .

 

Amazon is your friend
