What we found
We diagnosed the sinking pedal to a failed power brake booster together with deteriorated brake hoses that were no longer holding pressure. On a truck this age, the whole hydraulic side had aged together.What we did
Nick replaced the power brake booster and the worn brake hoses, then bled the system thoroughly to get all the air out and restore a firm pedal. Brakes are the one system where we do the job completely rather than patch the cheapest single part.How it turned out
A firm, high brake pedal restored, and a truck that stops the way it should again.A brake pedal that slowly sinks to the floor is a hydraulic problem and a genuine safety emergency — the system is not holding pressure. Do not keep driving on it; get it towed in if you have to.
Prices and times are what this job took on this vehicle. Yours may differ — we will tell you before we start, not after.
