Hi Guys,
New here, this forum has been a wealth of information for me so far and finally decided to register!
I bought an IS200 quite a while ago as a temporary get me around car whilst I fix up my others, but have ended up growing very fond of it and now have an appreciation of all Lexus motors!
However, the car is currently driving me crazy! I had the common seized front brakes issue so replaced both of the front calipers with 2nd hand replacements and this is when all my problems started.
After fitting the calipers and bleeding all the calipers, my brake pedal pushes down around half way and then slowly sinks all the way to the floor. When driving, i have hardly any breaking pressure until I pump the pedal a few times then it will stop very quickly. However after a short period of time (30 seconds) all the pressure will dissipate again. Things I have tried to resolve this issue which have had no effect:
- Bled all the brakes & Vacuum bled the ABS unit.
- Replaced the master cylinder with another which turned out to be the wrong one, which after a few pumps locked the brakes on completely until releasing the pressure from a caliper.
- Put original master cylinder back on, bled calipers & Vacuum bled ABS again.
- Replaced Booster & Master cylinder with the correct one, bled brakes & vacuum bled ABS again.
My brakes are still the same and i'm at a complete loss! Really want to get my car back on the road.
Any help would be greatly appreciated and once fixed I look forward to contributing to the forum with a working Lexus of my own
Many thanks,
Matt
