Brake booster and master cylinder upgrades

Looking at upgrading brake booster and master cylinder .

 

You putting on bigger wheels/tires, adding bumpers, armor, tents, gear that will add weight?

 

I got bigger tires lift bumper and everything else .my brake booster feels lik not working I replaced rear shoes and turned drums adjusted to tight. Front are new rotors pads and calipers just stock.

 

Just not much braking

 

Do a pressure flush with a high quality synthetic brake fluid. That will pull out all the old fluid and the new fluid is much more stable than OEM type fluid. A pressure flush should pull the old fluid from the ABS and everywhere else a regular bleed wouldn't get. You can get one from Harbor Freight if you have an air compressor or a good mechanic/brake shop should be able to flush it for you. Did this on ,my 6k pound Land Cruiser and made a noticeable difference.

 

I have blead system numerous times. What do know bout load proportioning valve would that make whole system bad and how do u bleed that.

 

How did you bleed the system? The service manual has a specific procedure. If you didn't bleed the LSPV you didn't do it correctly.

 

An extension to the LPV actuator rod is essential with a lift.
Without it you will have NO rear braking.

 

I never got extension for lpv. And bleeding normal bleeding of system from farthest , pump 10 to 20 pumps hold pedal, releasing air or till pedal is all the way down to floor, and repeat. when do u bleed lpv

 

Thankyou for the interchange booster and master cylinders

 

If you get to the point of not getting better braking after correctly repositioning the LPV arm and bleeding again, look into the Tundra brake upgrade.

On my 2003 I put on the OME suspension (~2" lift), a BAMF relocation bracket for the LPV and the stock brakes were crap when I was loaded up. So I did the Tundra brake upgrade with remanufactured 13WL Tundra calipers from Napa auto parts, EBC Greenstuff 7000 pads and StopTech slotted rotors. I didn't think about the braking power being weak ever again - even while loaded up.

 

This is hilarious for those of us with Tundra's. Probably the single biggest complaints about the 1st gen Tundra is the 13WE/WL calipers. That's good that they help the Taco's though.

 

Whst steps to bleed system with lpv. And I'll get the bracket I havent done 13 wl I have everything but the brake lines. And the booster someone mentioned, does it matter on 2 or 4wd
