Help, problem with locking front brakes.

Hello,

I have a 2008 Tacoma TRD Off Road and I am experiencing inconsistent locking front brakes. I'm trying to diagnose if the problem is the brake booster, master cylinder or ABS unit. Looking for any advise you can offer.

Thanks

Dave

 

Does it hang up like after using them?
Does it seem to pull to one side like dragging a brake?
A sticky piston on a caliper can do this.

 

It seems to be sticking both brakes on the front only. It is inconsistent and seems to be worst in primarily very cold weather.

 

Welcome.
I thought the OR has the electronic brake booster...
How does the pedal feel now, compared to beforehand?
How much fluid is in the reservoir?
What do the rotors/pads look like?
Do you hear the abs unit when it happens?

 

Start with Flushing the brake system.

 

Any rust ?
