I Have a 96 toyota corola serious brake issues. Front right brake caliper is locking up doesn't happen all the time but is starting to happen more often. I changed the brake caliper and bleed all the lines was working great for a while then the problem started all over again not sure what it could be. before I start throwing any more money at this car I hope you can steer me in the right direction. Thank you!

Changed caliper,new pads and rotors in the front
Hi,This is going to be a bad brake hose on that side. There is an inner rubber to the hose and it will collapse when brake fluid gets too hot. When it does this, it acts as a one way valve, allowing fluid and pressure to the caliper but preventing it from returning until the fluid cools off. This is usually caused by not flushing the fluid every 2yrs and having condensation buildup in the fluid which lowers the boiling point of brake fluid.Easy test for this to confirm. Take on test drive until it starts locking up. Pull over and open the caliper bleeder screw for about 30 seconds on the side locking up. Now tighten bleeder screw and pull forward a few feet to confirm that caliper released. If it has, replace the hose and flush your brake fluidIf, by chance it hasnt, then it will be the master cylinder, but this is a rare event for it to be that.Please note, your Deposit doesn't constitute a payment.

Changed the hoses still locking up.
Hi,did you do the test I gave you before changing the hose to verify that hose was bad?
No I got the lines for a good price so I change the two front and bleed the system a still the same problem. So I know its not the lines is their a way to check the master cylinder? Thanks
Hi,take for the test drive and when it locks up, pull over and loosen the two lines at the master cylinder enough for brake fluid to drip out. allow it to bleed for about 30 seconds and then tighten lines and drive forward to see if wheels have released
So if it
So if it releases that the master cylinder is no good?
Hi,if the wheels free up when master cylinder lines are loosened, then its a bad master cylinder. If not, then bad booster
Thank you very much! I'll keep u posted on what I find out
Hi,ok, sounds good
